So what is the complaint that tear gas was used? It's used all the time it's a normal crowd control measure. The galaxy is watching? Please.
I don't think people sitting in traffic qualify as a crowd that needs control.
This is not justification in itself. It's abused as a crowd control measure frequently. This rendition doesn't gain some special immunity to that abuse.
Funny that this "proud Mexican" has such a long story to tell but zero proof to show. Neither he nor his girlfriend were able to record any of that while sitting comfortably in their car?
We're on Hacker News and complaining that people don't want to record their entire lives on the internet?
