Always document everything possible. File a formal written complaint. Why?
Well, to protect others and yourself. Most asshole cops do the same number to people over and over. If you at least get it documented, there is a history started. someone has to do it. Maybe you run into officer shitty pants again. Maybe, this time there is no dog...maybe he tells you "Restrain your self or I'll plug you like I was going to plug your dog....bitch." Maybe I'm being sarcastic but you get it though I hope. Most people think the man is too big to be silenced every now and again. Or you can do what I myself and most others do at times. Let it go, life is too short to worry or stay upset about a little angry man with a badge. There's so many other thoughts that can be filling your head......like telling me what Tissue culture is about, or give me info on it...links to site you know.
