My question involves criminal law for the state of: California
Here is the video showing the male striking the female during a street brawl & protest.
Here is what we know, feel free to add more details if you have any.
Woman:
The woman dressed herself to represent a political group known as Antifa. Antifa is known to mace & attack people who protest against their political ideologies.
The women showed intent on facebook to 'scalp 100 nazis' before the event.
Man:
The man is affiliated with a controversial group that condones white supremacy.
The male has a history of violence in the form of armed robbery and a background in the military.
Was it legal to punch this woman standing her ground in this scenario? The police did not intervene for some reason.
Disclaimer: I'm in no way condoning assault, white supremacy or attacking people for their beliefs.
I believe it is still illegal to strike someone in this matter given the situation. What do you guys think?
