As a former prosecutor I can say that the vast majority of cops are good, decent, dedicated professionals.
That doesn't mean I will engage in an unwanted consensual encounter with one if he/she sees me open carrying. That doesn't mean I willconsent toa search of my effects. That doesn't mean I will waive my right to remain silent. Professional officers will not be offended by any of these refusals. They may have the authority to approach me, but I have the right to refuse to play along.
In my opinion, the main reasonthat many people, not just OCers, dislike and/or fear the police is because the police are tasked with enforcing way too many intrusive victimless crimes. The guy who works hard all week but wants to smoke a joint before he listens to his favorite band play Saturday night has a legitimate reason to fear the police. The guy who goes about his business like everyone else but who chooses to openly carry a sidearm has a legitimate reason to be wary of some of the ignorant officers out there. The guy who pays thousands of dollars in taxes, but who has a couple of questionable deductions has a good reason to fear the agents of the state. I could continue.
If the police were only tasked with enforcing law against victimizing other people, then the respect for them would go up immensely overnight. But as long as they are the arm of the do-good, nanny-style, we-know-better-than-you-do-what-is-right-for-you-and-your-family government, they will continue to be viewed with suspicion, distrust, and yes, occassionally hatred, by freedom-loving Americans.
