re: #5 CuriousLurker

On the Los Angeles Red Line are late teen and twenty something security guards/fare inspectors. Not well paid. They have a protocol of how to evaluate a suspicious package. First they try to find the person the package belongs to in the immediate area. If they can’t find the owner they get the real police. Who have bomb dogs. If the dogs react, everyone will be late getting home. If not, the bag is removed.

None of this is harder to learn than bagging groceries or making a burger on a grill at McD’s. Bottom line is that security is not taken seriously until something awful happens.
