Unless it's against some kind of law for someone to observe police, you should know better than that. And seeing the way these animals acted, I'd say being concerned for the welfare of the downed biker is a perfectly legitimate reaction.
>Being nosy is the part that didn't end well.
Not illegal, and certainly not worth violent treatment and solitary confinement.
>What are they supposed to do when you ignore them?
If they're breaking this minute of a law? I don't know, issue a fucking citation? If they're not breaking a law, leave them alone? You know.. sane, professional, calm behavior that police SHOULD aspire to?
By the way - I find it interesting that people are referring to the police report as if it were the gospel where the author's article is just some random nut's view. Do you really think a police force that has no problem with brutality and unjust imprisonment really has any moral issue with filing an untrue/misleading report that makes them look better?
