Audio file of the 911 call before "punch"
QUOTE: She's trying to pick a fight with anybody, she almost hit an old man," the caller said. "She was talking about how she got out of prison and 'I'll beat up all you guys.'"... END QUOTE
Other information not mentioned previously in thread (at least as far as I know). The man filming (Mr. Green) was also homeless. The punched lady (not by fist, but via elbow arm) had a previous history (thus I guess why they knew her by name) with police (at least 4 arrests, twice charged with assault on police.
Before the video featured in the main tread title. It was said the lady pushed both officers. As far as I know, there is no video of this to verify (but the bus has a picture taker but would not release it to public, ongoing investigation). Just witnesses reports.
QUOTE:One witness told NBC LA that prior to the exchange caught on Green's video, the woman shoved both deputies so forcefully that he thought she was on PCP. END QUOTE
