Amazing

What I found on a forum at AR15.com; a reply from a supposed law enforcement officer to a comment on officers and free speech:

It would be my contention, quite possibly wrong, that any Officer, as an agent of the .gov, could be liable for any breach of a citizens First Amendment protections.

...and you would be wrong. Anyone who uses that kind of language at that volume is certainly guilty of DOC. Moreover, when you jump up in a cops face and start screaming anything at him then you are certainly displaying aggressive behavior. I have no obligation to let you take a swing before I defend myself...I just need a reasonable belief that you are about to assault me. It all depends on how the report is written, and I write it.

You might keep in mind that an awful lot rides on that written report, and you don't have a lot of input into its content. While it is being typed you are in a holding cell at best, and the ER at worst! If you want to screw with the bull, don't be surprised when you get the horns!

Emphasis added. Law enforcement officers are trained to take control of situations. They are also trained as though they are all that matters, meaning their safety is of the utmost priority, and their interpretation of foul/loud/critical language as imminent physical danger reflects this.

You can bet if a cop screwed up his situation, he'd naturally have a tendency to clean it up a bit in his written report. And also quite naturally, his word is all too often taken over that of the accused.
