In 40 years I've only had one bad experience and yes it was an illegal search. One local cop in PA having a bad day decided to pass it on to me while his partner and I stood and watched in disbelief. All other experiences were very professional.
You must not live in New England where 90% of the police officers routinely break the law they are sworn to uphold and treat citizens they come into contact with as though each and every one of them is a dangeous felon with no rights to even look them in the eye, let alone speak.
"law and order" is difficult to associate with law enforcement officers who have no respect for anything of the sort being applied to they themselves.
