"Police say the shooting call came from a cell phone but they still don't know who made it or why."
Some anarchist, knowing Williams is deaf, made a cell phone call that would surely bring armed police to Williams' home.
(IIRC, Islamo-terrorists are very good with anonymous cell phones)
Relying on the propensity for police to use a TASER instead of a gun, the plan worked beautifully.
Note to cops ... they're trying to make bobbies out of you.

I don't know about bobbies. Looks like the cops were more boobies. ;-)
