Do policemen have the right to ill treat honest, law abiding citizens like this?

the more you pile on the praise the more arrogant they become, people fail to realize it is a job they are not heroes, I am sure there are cops out there that believe they are serving there community but the vast majority of them believe there own hype. I have several "friends" that are police officers in cities in Fl, I put it in quotations because now all there friends are other police officers because they understand each other, I have watched my son go from a polite compionate young man to a arrogant rude and condescending man in the five years he has been a police officer, most cops are cops because they are unable to anything else
