High School Teacher Assigns Movie-Plot Threat Contest Problem

In Australia:

A high school teacher who assigned her class to plan a terrorist attack that would kill as many innocent people as possible had no intent to promote terrorism, the school principal said yesterday.

The Year-10 students at Kalgoorlie-Boulder Community High School were asked to pretend they were terrorists making a political statement by releasing a chemical or biological agent on “an unsuspecting Australian community”.

The task included choosing the best time to attack and explaining their choice of victims and what effects the attack would have on a human body.

“Your goal is to kill the MOST innocent civilians,” the assignment read.

Principal Terry Martino said he withdrew the assignment for the class on contemporary conflict and terrorism as soon as he heard of it. He said the teacher was “relatively inexperienced” and it was a “well-intentioned but misguided attempt to engage the students”.

Sounds like me:

It is in this spirit I announce the (possibly First) Movie-Plot Threat Contest. Entrants are invited to submit the most unlikely, yet still plausible, terrorist attack scenarios they can come up with.

Your goal: cause terror. Make the American people notice. Inflict lasting damage on the U.S. economy. Change the political landscape, or the culture. The more grandiose the goal, the better.

Assume an attacker profile on the order of 9/11: 20 to 30 unskilled people, and about $500,000 with which to buy skills, equipment, etc.

For the record, 1) I have no interest in promoting terrorism—I’m not even sure how I could promote terrorism without actually engaging in terrorism, 2) I’m pretty experienced, and 3) my movie-plot threat contests are not misguided. You can’t understand security defense without also understanding attack.

Australian police are claiming the assignment was illegal, so Australians who enter my movie-plot threat contests should think twice. Also anyone writing a thriller novel about terrorism, perhaps.

An AFP spokeswoman said it was an offence to collect or make documents preparing for or assisting a terrorist attack.

It was also illegal to be “reckless as to whether these documents may assist or prepare for a terrorist attack”.

Detecting Cheating at Colleges

The measures used to prevent cheating during tests remind me of casino security measures:

No gum is allowed during an exam: chewing could disguise a student’s speaking into a hands-free cellphone to an accomplice outside.

The 228 computers that students use are recessed into desk tops so that anyone trying to photograph the screen—using, say, a pen with a hidden camera, in order to help a friend who will take the test later—is easy to spot.

Scratch paper is allowed—but it is stamped with the date and must be turned in later.

When a proctor sees something suspicious, he records the student’s real-time work at the computer and directs an overhead camera to zoom in, and both sets of images are burned onto a CD for evidence.

Lots of information on detecting cheating in homework and written papers.

Cheating on Tests, by the Teachers

If you give people enough incentive to cheat, people will cheat:

Of all the forms of academic cheating, none may be as startling as educators tampering with children’s standardized tests. But investigations in Georgia, Indiana, Massachusetts, Nevada, Virginia and elsewhere this year have pointed to cheating by educators. Experts say the phenomenon is increasing as the stakes over standardized testing ratchet higher—including, most recently, taking student progress on tests into consideration in teachers’ performance reviews.

Remotely Spying on Kids with School Laptops

It’s a really creepy story. A school issues laptops to students, and then remotely and surreptitiously turns on the camera. (Here’s the lawsuit.)

This is an excellent technical investigation of what actually happened.

This investigation into the remote spying allegedly being conducted against students at Lower Merion represents an attempt to find proof of spying and a look into the toolchain used to accomplish spying. Taking a look at the LMSD Staff List, Mike Perbix is listed as a Network Tech at LMSD. Mr. Perbix has a large online web forum footprint as well as a personal blog, and a lot of his posts, attributed to his role at Lower Merion, provide insight into the tools, methods, and capabilities deployed against students at LMSD. Of the three network techs employed at LMSD, Mr. Perbix appears to have been the mastermind behind a massive, highly effective digital panopticon.

Zero-Tolerance Policies

Recent stories have documented the ridiculous effects of zero-tolerance weapons policies in a Delaware school district: a first-grader expelled for taking a camping utensil to school, a 13-year-old expelled after another student dropped a pocketknife in his lap, and a seventh-grader expelled for cutting paper with a utility knife for a class project. Where’s the common sense? the editorials cry.

These so-called zero-tolerance policies are actually zero-discretion policies. They’re policies that must be followed, no situational discretion allowed. We encounter them whenever we go through airport security: no liquids, gels or aerosols. Some workplaces have them for sexual harassment incidents; in some sports a banned substance found in a urine sample means suspension, even if it’s for a real medical condition. Judges have zero discretion when faced with mandatory sentencing laws: three strikes for drug offences and you go to jail, mandatory sentencing for statutory rape (underage sex), etc. A national restaurant chain won’t serve hamburgers rare, even if you offer to sign a waiver. Whenever you hear "that’s the rule, and I can’t do anything about it"—and they’re not lying to get rid of you—you’re butting against a zero discretion policy.

These policies enrage us because they are blind to circumstance. Editorial after editorial denounced the suspensions of elementary school children for offenses that anyone with any common sense would agree were accidental and harmless. The Internet is filled with essays demonstrating how the TSA’s rules are nonsensical and sometimes don’t even improve security. I’ve written some of them. What we want is for those involved in the situations to have discretion.

However, problems with discretion were the reason behind these mandatory policies in the first place. Discretion is often applied inconsistently. One school principal might deal with knives in the classroom one way, and another principal another way. Your drug sentence could depend considerably on how sympathetic your judge is, or on whether she’s having a bad day.

Even worse, discretion can lead to discrimination. Schools had weapons bans before zero-tolerance policies, but teachers and administrators enforced the rules disproportionally against African-American students. Criminal sentences varied by race, too. The benefit of zero-discretion rules and laws is that they ensure that everyone is treated equally.

Zero-discretion rules also protect against lawsuits. If the rules are applied consistently, no parent, air traveler or defendant can claim he was unfairly discriminated against.

So that’s the choice. Either we want the rules enforced fairly across the board, which means limiting the discretion of the enforcers at the scene at the time, or we want a more nuanced response to whatever the situation is, which means we give those involved in the situation more discretion.

Of course, there’s more to it than that. The problem with the zero-tolerance weapons rules isn’t that they’re rigid, it’s that they’re poorly written.

What constitutes a weapon? Is it any knife, no matter how small? Should the penalties be the same for a first grader and a high school student? Does intent matter? When an aspirin carried for menstrual cramps becomes “drug possession,” you know there’s a badly written rule in effect.

It’s the same with airport security and criminal sentencing. Broad and simple rules may be simpler to follow—and require less thinking on the part of those enforcing them—but they’re almost always far less nuanced than our complex society requires. Unfortunately, the more complex the rules are, the more they’re open to interpretation and the more discretion the interpreters have.

The solution is to combine the two, rules and discretion, with procedures to make sure they’re not abused. Provide rules, but don’t make them so rigid that there’s no room for interpretation. Give the people in the situation—the teachers, the airport security agents, the policemen, the judges—discretion to apply the rules to the situation. But—and this is the important part—allow people to appeal the results if they feel they were treated unfairly. And regularly audit the results to ensure there is no discrimination or favoritism. It’s the combination of the four that work: rules plus discretion plus appeal plus audit.

All systems need some form of redress, whether it be open and public like a courtroom or closed and secret like the TSA. Giving discretion to those at the scene just makes for a more efficient appeals process, since the first level of appeal can be handled on the spot.

Zachary, the Delaware first grader suspended for bringing a combination fork, spoon and knife camping utensil to eat his lunch with, had his punishment unanimously overturned by the school board. This was the right decision; but what about all the other students whose parents weren’t as forceful or media-savvy enough to turn their child’s plight into a national story? Common sense in applying rules is important, but so is equal access to that common sense.

The Bizarre Consequences of "Zero Tolerance" Weapons Policies at Schools

Good article:

Zachary’s offense? [He’s six years old.] Taking a camping utensil that can serve as a knife, fork and spoon to school. He was so excited about recently joining the Cub Scouts that he wanted to use it at lunch. School officials concluded that he had violated their zero-tolerance policy on weapons, and Zachary was suspended and now faces 45 days in the district’s reform school.

[…]

“Something has to change,” said Dodi Herbert, whose 13-year old son, Kyle, was suspended in May and ordered to attend the Christina district’s reform school for 45 days after another student dropped a pocket knife in his lap.

[…]

The Christina school district attracted similar controversy in 2007 when it expelled a seventh-grade girl who had used a utility knife to cut windows out of a paper house for a class project.

The problem, of course, is that the global rule trumps any situational common sense, any discretion. But in granting discretion those in overall charge must trust people below them who have more detailed situational knowledge. It’s CYA security—the same thing you see at airports. Those involved in the situation can’t be blamed for making a bad decision as long as they follow the rules, no matter how stupid they are and how little they apply to the situation.

Corrupted Word Files for Sale

On one hand, this is clever:

We offer a wide array of corrupted Word files that are guaranteed not to open on a Mac or PC. A corrupted file is a file that contains scrambled and unrecoverable data due to hardware or software failure. Files may become corrupted when something goes wrong while a file is being saved e.g. the program saving the file might crash. Files may also become corrupted when being sent via email. The perfect excuse to buy you that extra time!

This download includes a 2, 5, 10, 20, 30 and 40 page corrupted Word file. Use the appropriate file size to match each assignment. Who’s to say your 10 page paper didn’t get corrupted? Exactly! No one can! Its the perfect excuse to buy yourself extra time and not hand in a garbage paper.

Only $3.95. Cheap. Although for added verisimilitude, they should have an additional service where you send them a file—a draft of your paper, for example—and they corrupt it and send it back.

But on the other hand, it’s services like these that will force professors to treat corrupted attachments as work not yet turned in, and harm innocent homework submitters.

British High Schoolers Write About CCTV in School

If you think that under-20-year-olds don’t care about privacy, this is an eloquent op-ed by two students about why CCTV cameras have no place in their UK school:

Adults are often quick to define the youth of today as stereotypical troublemakers and violent offenders—­ generalisations which are prompted by the media—­ when in fact the majority of students at our school are as responsible and arguably better behaved then the majority of adults. Some commentators insinuated that we overheard adults talking about rights and repeated it. That notion isn’t worth the space it was typed upon. We are A-level politics students who have been studying civil liberties as part of the curriculum for the last two years. Sam campaigned for David Davis when he resigned over the issue of civil liberties and spoke at speakers’ corner about the issue. The criticism of our campaign only serves to illustrate the ignorance of adults who have surrendered within only the last few years our right to protest in parliament, our right to go about our business without being stopped and questioned by police about our identity and our affairs, and our personal privacy.

Eroding standards in schools and deteriorating discipline are down to a broken society and the failure of the education system. The truth is that we are whatever the generation before us has created. If you criticise us, we are your failures; and if you applaud us we are your successes, and we reflect the imperfections of society and of human life. If you want to reform the education system, if you want to raise education standards, then watching children every hour of every day isn’t the answer. The answer is to encourage students to learn by creating an environment in which they can express their ideas freely and without intimidation.

Update on Computer Science Student's Computer Seizure

In April, I blogged about the Boston police seizing a student’s computer for, among other things, running Linux. (Anyone who runs Linux instead of Windows is obviously a scary bad hacker.)

Last week, the Massachusetts Supreme Court threw out the search warrant:

Massachusetts Supreme Judicial Court Associate Justice Margot Botsford on Thursday said that Boston College and Massachusetts State Police had insufficient evidence to search the dorm room of BC senior Riccardo Calixte. During the search, police confiscated a variety of electronic devices, including three laptop computers, two iPod music players, and two cellphones.

Police obtained a warrant to search Calixte’s dorm after a roommate accused him of breaking into the school’s computer network to change other students’ grades, and of spreading a rumor via e-mail that the roommate is gay.

Botsford said the search warrant affidavit presented considerable evidence that the e-mail came from Calixte’s laptop computer. But even if it did, she said, spreading such rumors is probably not illegal. Botsford also said that while breaking into BC’s computer network would be criminal activity, the affidavit supporting the warrant presented little evidence that such a break-in had taken place.
