There's no way it won't escalate now that there's a body count, especially since there's cops included, but I'm still staunchly against the use of military force on our shores. Deal with individual criminals, don't make sweeping policies that catch up a bunch of innocent people and crush liberties for everyone. The worst thing possible to respond with would be some national level responses that interfere with rights and liberties of communities that don't even have riots ongoing in them, and even a proportional response to riots is extremely dangerous. Power used on looters can be power used on anyone else.
