The Security Risk of Special Cases
Police officers are permitted to bypass airport security at the Dublin Airport. They flash their ID, and walk around the checkpoints.
A female member of the airport search unit is undergoing re-training after the incident in which a Department of Transport inspector passed unchecked through security screening.
It is understood that the department official was waved through security checks having flashed an official badge. The inspector immediately notified airport authorities of a failure in vetting procedures. Only gardai are permitted to pass unchecked through security.
There are two ways this failure could have happened. One, security person could have thought that Department of Transportation officials have the same privileges as police officers. And two, the security person could have thought she was being shown a police ID.
This could have just as easily been a bad guy showing a fake police ID. My guess is that the security people don’t check them all that carefully.
The meta-point is that exceptions to security are themselves security vulnerabilities. As soon as you create a system by which some people can bypass airport security checkpoints, you invite the bad guys to try and use that system. There are reasons why you might want to create those alternate paths through security, of course, but the trade-offs should be well thought out.
