Is it time to start calling out bad cyclists?

Chap runs a red light, nearly hitting an old lady. I yell, and catch up with him at the next red. Am presented with a tiny, tiny Indian chap in a Playmobil helmet.

"What was that?"
"Mate, you nearly hit that woman, the light was on red."
"Rules are meant to be broken. You don't know who you're dealing with. I've got connections. Serious connections. I'll knock you out."
"Mate."
"I'll fucking shoot you. And your fucking family."

And he then ran a red to run away too. The big girl's blouse.

At that point I would have hit the cunt.
