Hmm. I might, depending on the details. Judging by the the outcome, it certainly seems to be a case of the officer taking an unnecessary risk.
This isn't the movies. But even if it was, the idea of police shooting at a suspect who is using a hostage as a human shield is questionable at best. Especially with a handgun. A sniper shot might be a different situation, but even in that circumstance, I happen to personally remember when a hostage was killed in an Orlando standoff due to a poice sniper's fatal error.
The point is, it's obviously preferable that the perp escape capture (temporarily, hopefully) than for a hostage to be fatally shot by police.
I'm sure the officer feels horrible.
Just tragic...
