PS, not that I, an aging gentle soul and learned legal scholar would ever advocate violence, but this is what many think should happen to your biker scum friends.

You are confused. They're not my friends.
It's more like I don't want bad legal precedent(s) to be further enlarged & enforced. That is all.
I'm an American. A Christian. An individual the Lord has spoken directly to, many times. Twice, two late-mornings in a row, He told me in His smallest voice --"you are free". So quiet His voice on those occasions --I almost missed it-- but I know the sound of that voice.
When hearing it the first time, I was puzzled, yet encouraged too. Hearing it again the very next day, when I lay foot-fall on quite possible the very same boards (same exact planks of a wharf on the West Coast) it stuck me. He can swear by none other than Himself. He does confirm His own words to us.
That was approximately 20 years ago by now. I'm still free.
I'm not even going to waste my time clicking on a youtube link that bears no labeling of what it is. Some bad thing you desire to happen to "bikers"? Careful what you wish for, amigo. You may not have the standing to be above the curses casually flung around. They can have a way of turning 'round and biting back. That's one of those "kids -- don't try this at home" kind of things...
