Being uncomfortable around Police does not mean a person is a criminal, a bum or a bad person.
Are most Officers good?... Yes. Are there some that have shown they can abuse the power given to them by their job?... Yes. Do the good Cops make the news?... Rarely.
Combine all that with the fact that Officer involved shootings increased 100% in that area over the course of last year, to a number greater than that or either New York or LA, and I can understand why some good people could feel uneasy around Police officers around that town.
The employee was put in a tough spot especially considering that every employee was put through "sensitivity training" last year. I don't think they handled it well, but I don't think the Police Officers Association needs to take their hurt feelings to Twitter either.
Everyone needs to stop being so damn sensitive and stop looking for something to be offended about.
