They sure do. They have an 'It's us against the citizens we are sworn to protect and serve mentality. Quite a few are just plain scared and paranoid of everyone except other cops. The also look at the law abiding citizens like "we know you are quilty of something but we just haven't caught you yet. Most of these types of cops(Law breakers in uniform) could not get a CCW Permit if they were civilians.When it is legal for cops to lie they will and it is legal for cops to lie. Cops seem to think that they are better than the people they are sworn to protect, just listen to a couple of cops talk with each other it is pretty evident.
I sometimes wonder who the police really "Protect and Serve". The Mayor and city officials. Most of the time they give lousy service with a bad attitude.
