Actually, you said--repeatedly--that these stops were random and used an incomplete example where nothing was found as evidence of that. You presented no evidence of your own and no refutation of that given you. You said that these weren't Terry stops and had "nothing at all" in common with a proper Terry stop. You flaunted your ignorance repeatedly, played the race card, and have had your butt handed to you by the guys who do this on the street and defend this in court.
It's not that you don't know what's going on; that's common and totally acceptable. It's that you embrace the public school self-esteem script of thinking that you opinion from ignorance is as valuable as educated opinions, and you refuse to do anything to cure your ignorance. To top it off, you act like a Democrat and try to move the goalposts and redefine your already stated position when fact runs against you.
By all means, be done with the thread and let the grownups talk. There *are* issues in play here, but you're a distraction from them.
"To spit on your hands and lower the pike; to stand fast over the body of Leonidas the King; to be rear guard at Kunu-Ri; to stand and be still to the Birkenhead Drill; these are not rational acts. They are often merely necessary." Pournelle
