I don't know Nigel, but the eyewitness reports I'm hearing from friends are very similar. I have no idea about the baby incident, but these thins do happen. Overall, the SF cops are handling this very well, but tempers do flare and cops lose their self-control as do any if us humans.

If it's any consolation, my Mom's local news is reporting that the peace protesters in SF are dragging people out of cars and killing them. No footage, mind you...
