And then there's the N. Hollywood shootout where LEO's were up against automatic rifle fire and only had shotguns. They ran into guns stores and grabbed some AR-15's to even things up a bit and after that incident, most police agencies started keeping an AR or similar semi-auto rifle in their squad cars.
Live and learn.
In the Miami shootout, most of the shooters were within 8 feet of each other, IIRC.
Evidently the feds were lousy shots.
