TSA employees have faulty criminal background checks
TSA employees with faulty criminal background checks
The TSA serves a very important and vital role in airline security, and all of their employees are required to pass security and background checks. However, those checks in the past have been less than thorough. For example, in 2004, the Department of Homeland Security (which includes TSA) released a report that stated that TSA had allowed some screeners to perform their duties before their criminal background checks were complete, and allowed others to continue working while problems with their background checks were resolved. Even if this problem no longer exists for current applicants and employees, a more serious problem may be that the current system of background checks may have allowed those convicted of rape and other sexually based offenses to join TSA.
