This being unaware of a second shooter is something that is remedied with proper training and mindset. I'm not trying to sully the fallen inocent citizen, I'm just hoping from this circumstance comes some good for others of us that choose to not be a victim of dirtbags.
my thoughts are with all of the families, friends, ci-workers of the slain victims. If there is some sort of judgement after death I hope the two cowards face it.
sad to hear they're from Lafayette Indiana.
You have to train for it, but it's still a huge uphill battle when you are 1) reacting to someone else's action, and 2) outnumbered. If you're ambushed by an accomplice you didn't know existed, it's going to boil down to being lucky if you prevail in my opinion.
Of course, training might make one reticent to engage until observing a little while longer of the circumstances allowed it.
So many what ifs.
