"According to the Government Accountability Office (GAO), TSA officials have long acknowledged the potential threat from airport workers, but deemed the threat a 'known and accepted risk.'"
In June 2015, the DHS OIG released a report which found that 73 aviation workers who held sensitive jobs within U.S. airports were found to have possible ties to terrorism, which their background checks did not reveal. In addition to these 73 individuals, the investigation concluded that thousands of TSA employee records were incomplete and contained inaccurate information. Without a comprehensive background check for employees, TSA does not have the ability to vet those individuals who may harbor ill-will toward the U.S. or have connections to individuals who do.
AMERICAN AIRPORTS: THE THREAT FROM WITHIN
House Homeland Security Committee Majority Staff Report
That is the main point in discussion, I think, and this is the point making things different.
Is hiring procedure the same, when I hire a mechanic for my car, and when an airline hires personnel? Of course not.
If the airline hires a psychologically unstable person, has any consequences? I don't know, but I doubt.
In our days, after so many people killed, by commercial airplanes, and after millions and millions spent for air traffic security, the fact that any employee working in baggage department, can easily enter the cockpit and takeoff from a fully working airport, has some consequences for anyone? I don't know, but I doubt.
If someone flying a drone, comes "near something", will have consequences? I don't doubt at all, he will.
In Greece for example, the fines for everyone who "flies" even a toy drone, are the same with those for big commercial aircraft. They heard that a drone is "aircraft " and they just copy-paste the law.
If you try to explain this in here, some will try to explain you the law again and again, and at the end, they'll say you're an idiot and you don't understand the laws.
