I'm not sure what constitutional violations you're seeing on Cops. But for me personally, I don't really care if every letter of the law gets applied to the typical low-lifes that I see on that show. I think the police have a very tough job -- I admire what they do.

So, in other words, it is acceptable for one person to violate the law to apprehend another person voilating the law. Nice!
