I am in no way insinuating that LEO's look down on or think less of non-LEO's, but I just assume it's easy to adobt a view like that.
I have felt it quite a few times here (Denmark).
Well, I can only speak for inside the U.S. The rest of the world isn't bound by our laws.
Your ethics should guide your choice of profession. If you enforce laws that are immoral, you're just as much a part of the problem as the legislature that made the law. LEO have great amounts of discretion in what they enforce, the pinheaded cops that enforce the laws that are immoral deserve their kharmic fate.
In every profession that I have had, including software programmer, web design, police officer (current), network administrator, I always ran into something which I either didn't believe in, or like.
Whether it was my web design work on a porn site, which I may not like or support, or writing software just to make sure that people fall into a late fee system with their bills. The point is, in jobs, sometimes a person has to do something not because of their support for the morallity or ethics of the job or task, but because they need the income.
If I didn't need money or income for my family, I would just as soon live out in the middle of nowhere, own some horses, play with ham radio towers several hundred feet high, own an outdoor gun range, and a pond to fish in.
But reality is just the opposite. I do need money and a steady income. I go out and enforce laws, as stated before, there are "shall" laws and "may" laws.
There are many times as a police officer you do your job simply by being present, or by schooling somebody. If I can end a traffic stop simply by explaining to the person that they need to get a tag, or remove the border around their license, or even stop before making a u-turn, then great. That is what I try to do most of the time.
We leave the traffic enforcement up to the STEP (traffic enforcement) officers who are specialized in that. Traffic stops are actually extremely dangerous. Normally not even worth it.
Me personally, I'm a huge 2nd ammendment supporter. I have never hasseled someone over a knife or a gun. Now if a person were to put their hand on a knife or gun during my "field interview," they would be told to remove their hand. Simple as that.
Otherwise, I simply will ask someone what they have because I'm interrested. I give people the same respect they give me. I'm sorry but when people start the conversation with "What the hell do you want you idiot?" (And it happens more than you think), I won't treat them the way I do my mother.
