Thanks, that does help. Between what people here have said and what I've read at the police forum I linked to, most of my issues/concerns/questions have been addressed. The only thing I'm interested in hearing the officers address further is the issue of the taser beign in the possession of the assailant. Given that in this case he was apparently zapping them with it directly, I'd be curious to know if their approach would have been different if he were not able to be within arm's reach, and if the taser had already been discharged. Sounds like it wouldn't have made much difference, though.
