Don't run at the cops with a gas can in one hand and a lighter in the other. There is no possible good outcome to that situation.
Commenters elsewhere are discussing various aspects of it, but in the end, it seems like a situation that was destined to be a trainwreck from the start. Let's break it down:
An intoxicated man (funny how so many police reports start like this) does something that gets the heat called on him. The five-oh shows up (at this point we have now reached a statistical certainty that someone's going to jail or the ER) and, according to the police report, our soon-to-be crispy critter runs right at the cops, gas can in one hand and ignition device in the other. Now, in the old days, a particularly ninja-like cop might have attempted to get the lighter away from him with only a few broken fingers and a dislocated shoulder, and maybe given him a good hickory shampoo in the bargain. Or maybe they'd have just shot him.
But now we have given the police a magic wand! A 100%-safe, lawsuit-proof gizmo to prevent said hickory shampoos and shootings. Only this time there's a bit of a complication...
I don't know what can be done procedurally from the LE side of things to fix this. For my part, I'm going to avoid getting 'faced in such a way that someone feels compelled to call the po-po on me, because if there's one thing I've learned from watching COPS during baseball rain delays, it's that "Drunk + Cops + (no shirt/flip-flops) * nosy neighbors = Nothing good."
