with 70,000 security personnel deployed to prevent a repeat of the violence seen on October 17

How much do you want to bet that the vast majority of the violence was committed by "security personnel"?

Almost every time there's a shitload of cops and other "security personell" at any protest, it drastically escalates rather than limits violence.

Because cops love to beat up protesters just as much as they love to murder black people, if not even more.
