I was pulled over for speeding on night after having been out at the club. I had had a drink earlier and had not eaten anything since, just one drink about two hours before. Needless to say, I was terrified. I was wearing a short school girl skirt, thigh highs, white blouse tied about my waist. This was the first (and only) time I had been pulled over dressed.
Since he could smell alcohol on my breath, I had to go thru the whole routine. I was able to pass all the tests, speak coherently, but was shaking somewhat due to nerves and having no idea how I would be treated. I needn't have feared, I was treated respectfully, nothing was mentioned about how I was dressed, and I was ticketed for speeding and sent on my way. Did I say this was in a very redneck town?
All that said, I have worked around law enforcement indirectly for years as an equipment vendor. I've seen the (usually young) power hungry ones, a few corrupt, but most have been very professional. I had one sergeant who became friends with me who was killed on a domestic violence call. Those are the most unstable calls. In this case, the woman who called, who he was protecting from having the crap beat out of her, stabbed him in the back with a butcher knife because he was arresting her boyfriend.
So while there are bad officers, just like there are bad in every field, they do have a very dangerous and difficult job, and the majority really do have your best interest in mind.
