Re: No rent-a-cops on the front lines
Again, the critical question is: are the "rent-a-cops" being hired by airports, or the airline companies? I really think this might make all the difference in how diligent one is in hiring them.
It is worth noting that most people and companies who can afford it hire "rent-a-cops" to protect them instead of relying on the government police forces. I'm sure this isn't just because they love to spend money.
