You omitted some of the dialog in your transcript excerpts. Just before 2:07, EBM stepped off the bus, said "... hit me first, he hit me in the face! It's f'n self-defense! Don't f with me!" and was walking away from the bus.
Then the black dude while standing safely inside the bus said "Yeah, next time, I'll f you up!". Leaking black guy doesn't know when to give it up, is a glutton for punishment.
When it went viral on the Internet, people tracked down the black gal who stole EBM's grocery bag, and showed her name, address and pictures of her home in Oakland, challenging others to harass her for stealing the Epic Beard Guy's belongings. Isn't the Internet fun?
Has to be an early contender for Darwin Award...or who knows, mebbe it was HER gang initiation.
