Only missed 42 times. Fired 110 rounds... "I am" a shooter And in order to maneuver on your target you need to suppress your target to keep his head down so he can't shoot back. I think that 110 round is pretty disciplined. 68 hits can take a good SWAT team second to achieve.
The concept of suppression fire is a myth created by those who wish to justify bad shooting. Every shot should be well aimed at the intended target. If you're providing cover for a team member who is in an exposed position then you continue to aim in the direction of the target and fire only when you have a shot. You don't just pray and spray and hope you're getting close enough to scare the guy into staying down.
I worked with some of the best marksmen the U.S. military has to offer. If we so desired we could easily put 68 rounds into a target in a heartbeat. The point is there is really no reason to ever do so. Especially at close range 68 rounds isn't going to do any more than a well-disciplined, well-aimed, well-placed double tap will.
Granted, SWAT tactics can be different in that they don't have to worry about conserving ammo for the next firefight or that ambush on the way back home, but I still have a hard time, for reasons I've already pointed out, justifying their actions in this case.
