It’ll be street violence, anarchy, terrorism etc… low intensity conflict.

3 masked man enter a pub and try to steal

owner there has had enough fight back with something

some guys side with him

3 now unmasked man of a certain group die (doesn't matter which)

police arrest the ones that defended themselves

their families protest, police arrest them

now other ppl protest, not enough police to arrest them all

it becomes violent, it expands to most town center of important cities

Executive resigns as they don't want to deal with all that shit

now chaos reigns till enough violence pushes all rioters into submission

Luckly it doesn't transforms in a us vs them, instead in a all vs gvnmt fight

worse case it becomes a three way fight, then you have a real civil war.

no need for guns for violence, just enough ppl that had had enough
