Yes indeed, a social war that might require "emergency laws" that will never go away.
As far as tasers and sucker punches, another common tactic is to target whites on bicycles. A person on a bike is an easy target, to knock down or even sucker punch in the jaw while he's passing. With the hands on the grips and the jaw sticking out, a bike makes one an easy target for a sucker punch.
Situational awareness is even more important on a bike as when walking. If I'm not going to walk close to a bunch of thugs, I'm not going to bike close to them either. And you can steer the bike with one hand while the other reaches for your sidearm if you suddenly notice a bunch heading for you on an intercept course.
