I'm of two minds on this one. A large powerful man on mesc, and who knows what else, can be almost impossible to stop short of lethal force. I was a prison guard and even at my size was more than once nearly laid out by a runt on speedball. Whatever that is. I don't really know anything about modern recreational drugs but 'speedball' sounded cool, and I more than once bounced a lead sap off of the brainhousing group of someone flying high and got nothing but a barely audible grunt in return, so the billyclub deal isn't guaranteed to work.
Nowhere in the article is any reference made of an attempt to Tase the guy, but that doesn't mean they didn't. Problem is, the cops, particularly California ones, aren't exactly known for their less than lethal approach to anything. And the fact that Reginald's name was revealed but not the name of the cop that killed him really bothers me. You try it. Even after a good shoot the cops are going to spread your name like wildfire.
