I've had several people go through our simulator (Milo, makes FATS look like an early NES video game) totally change their opinion of police.
We have the ability to chang the course of the scenario as it is running…shoot, fist attack, comply, fake comply, second attacker, victim family member turns attacker, etc. Even have scenarios where you're out with your family and stuff goes down. Talk about tunnel vision. "Not bad but you shot your kid here, and here, and here. And put one through that door your wife just walked through. Want to try this one again?"
