I agree that, for the most part, it's likely there aren't many Christmas cards exchanged by Law Enforcement Officers and TSAers.

There are likely politics involved between police brass and the TSA. And I think all parties involved would rather just keep feathers unruffled just for the sake of trudging through eight-hour workdays.

In the long run, the crap the TSA does in front of law enforcement officers probably does build up in their mind, and over time would probably give extra incentive for the LEO to really put the screws to a TSAer if and when the time becomes necessary to issue bracelets.
