Join the NMA, they're the only organized defense at this point.
Naaman - to your point about justifying that pulling people over catching criminals etc.. another way to do that is to hang out where criminals commit crimes, to guard houses of women that are being threatened etc...
Finding an excuse to pull someone over, setting 'speed traps' (not limits) that have no impact on public safety, that are COUNTER to public safety all in the name to see what the law can nail them with is not a trait of a free society. It's not much different then pulling someone over because they look like a Jew (in the 40s).
I respect Law Enforcement. They put their lives on the line every day and more than seldom they catch bad guys. I am very concerned about the culture that it breeds. It's not the people, the people are you and I, it's the culture.
For exampl, I've found in my experience that about 1/3 are very nice and professionals (some of which I wrote letters of recommendations to the police seargent), about 1/3 run around on high horses saving the world by giving expired tab tickets after 20 minutes of being pulled over in the middle of morning traffic and about 1/3 are complete dicks that should be out of a job - and that would be out of a job in any other profession faster than you can say egg mcmuffic sandwitch. There is absolutely no reason that any public or private professional should be a dick when they are carrying out their job. Period, no ifs & butts about it. However, you and I both know a number of cops that are.
So let me ask you this - why is that true? And you know it's true. I'll tell you why, what my cop friend told me:
UNIONS.
