I was a Deputy Sheriff for 7 years in a full service Sheriff's Office where we answered 911 calls and patrolled streets (most Sheriff's in NJ don't answer calls or have a patrol division). I was in an area of about 100,000 locals with 2 million annual visiting tourists to Mt Rushmore every year and another 500,000 to 1 million bikers coming to the Sturgis Rally every August. We had every crime the major cities have, just not always as often as they have it, but I know what its like to be a cop. Job #1 is stay safe and go home at the end of the day. That does not mean you can't treat people with RESPECT. We had a good relationship with the community because the effort was made to be professional, even when tackling someone and had cuffing them. I've had people apologise for resisting because I pick them up, dust them off and continue calling them sir as I put them in the back seat for that trip to jail.
With my experience and training in the profession (I'm no longer in LE, I'm back in the military) I would agree with most of you that the culture within the law enforcement community in NJ is bad. These cops have the perception as being assholes because they are robotic and impersonal and talk to people like they're 2nd class citizens. They really have a bad way of projecting themselves and they are either not aware of it or do not care. I suspect it's a bit of both.
They probably don't care that people don't like them because they deal with 1% of society but that 1% is always the bad people. It's easy to get into your mind that "everyone is a criminal" because everyone you deal with is a criminal. After a while, if 100% of the people you deal with are criminals, you think 100% of society is that way and you start treating them that way.
What they probably are not aware of is the fact that a lot of citizens already have a disdain for the government as a whole because we are over-taxed, over-regulated and are sick to death of crooked politicians at every level from local school boards all the way up to the Governor. Cops are part of the same government so their image is affected by that as well.
I'll end this here since its really off topic for the thread title.
