For civilians, it can be hard to understand just how quickly police officers must decide whether or not to shoot a knife-wielding attacker.
This amazing bodycam video of Chicago police officers having to make that decision in order to potentially save a fellow officer's life is an excellent example of how fast an individual with a knife can attack an officer - even after being tased.
Watch this video and see if you think the police officers involved made the correct decision to shoot the man with the knife.

WARNING: The man does not survive and this may be difficult for some to watch.~~~~~~
