There is probably a gang war in progress.
It likely started with the death of Ramon Ruano, who was gunned down in a parking lot. This was followed by another homicide of a man being stabbed to death, dropped off at an ER by persons unknown.
I truly doubt that gang members were holding a car wash to raise money for Ruano’s family. I’m guessing that they were friends of his, and they thought he was murdered by the gang whose colors the man with the dog was wearing.
Importantly, the dog owner is either highly stupid, or a gang member himself, for wearing gang colors in a gang neighborhood: “wearing a red sweater and a red Boston Red Sox hat”, which is gang wear of the Bloods gang.
“Rivals with Crips and Black Gangster Disciples. Red Bandanas and shirts and Boston Red Sox hats (for the letter B) Five-point stars, pitchforks pointing down. May cross out the letter “C” in writing Graffiti includes “CK” for “Crip Killer.”
CK? So they’d better not wear anything with the Calvin Klein logo, either.
