Koolau, I think you watch too much television, Hollywood does not reflect reality.
Guilty as charged Malcolm2. I love L & O and I root for the defendant as often at I root for the cops and the prosecutor. I love "Justified" and Breaking Bad". 95% of the folks portrayed in these shows are "bad" - including several LEOs. It's clear to me that the shows I tend to like have a certain moral ambiguity. I gave up on "black hats" vs "white hats" long ago.
But just because these shows are produced by Hollywood does not mean that the techniques they show (getting confessions, over charging defendants, coercing witnesses, etc.) do not happen. Maybe they don't happen as often as these shows portray, but that doesn't mean that they don't ever happen.
Minor as it may sound both DW and I have experience with LEOs attempting to extract a guilty plea (in these cases, for speeding). They lied and they threatened massive overcharging when they had no proof of speeding. My officer started his "schtick" by saying (exact quote) "There are several things I can 'GET' you for." Full disclosure at least in my case. I WAS doing 40 in a 35. But NO ONE on that stretch of road ever gets pulled over for 40 in a 35. Think what you will of me for "getting away with" 40 in a 35.
Nodak's story of the Eagle feather is also a joke, post a link.
I don't have a reference for you and MAYBE it never happened. But, if the law is on the books, it has either been used against someone or it WILL BE in the future. My point (backed up by the lawyer in the video) NO ONE can be aware of all the possible laws he could possibly break. If law enforcement wants to charge YOU with a crime, they can find a way to do it in today's environment of intricate layers of codified regulations and rules. I don't believe it happens on a massive scale, but an individual never knows when he might innocently fall under suspicion. At that point, law enforcement has a huge arsenal at their disposal to "get" you if they choose to.
Honest people (most of you) should just keep being honest. Don't commit a felony. If you do, by all means get a lawyer (a good but honest one) and hope you are one of the criminals that get off.
I think my point is that "honest" people DO commit crimes these days. They don't even know it and they had no intent. But "intent" is not a factor in most crimes (especially environmental, tax, ATF regulations, etc.). As always, YMMV.
