I would shoot 'till he drops, then secure him. After reading him his rights, I'd go hi-five the rest of the team. Then I'd get everyone on the same page, note wise. All this shouldn't take more than 30 minutes or so. Then I'd check on the perp and see if he was still breathing. If not, then I'd call for an ambulance.
Hey, that was the gameplan for the Hollywood bank shootout, remember? He laid in the street in handcuffs for 27 min. and bled to death.
