content: Yeah, hollywood doesn't know how guns work, but if you're referencing the real church shooting that happened then... Shot placement: people are surprisingly hard to kill, shooting them in the limbs are stomach are not good ways to do it.  Weapon choice: types of ammo in ballistic gel A .45 is roughly 20%+ more powerful (muzzle energy) Time: In the church situation we don't know exactly how quickly people died after being shot (it might be public knowledge? I don't know, but it's certainly not common knowledge). Even inaccurate hits would bleed out if left unattended long enough (compared to this which is on camera). Ultimately this is sad and I wish people would stop being dickheads of insignificant things.
