I'm a law & order kinda guy, and I think you should in general obey a LEO's commands when they are trying to get control of a situation, and when they're actively fighting with police, I think pretty much most bets are off. But that's a little over the top even for me.
Shooting looters in a widespread riot situation may be a different story though.
