Lets look at that. Two officers got to the shooters door after 16 minutes. They know its automatic rifle fire. All they have are pistols and vests capable of stopping pistol rounds.
If you go in you are instantly in a fatal funnel facing down a fellow that has weapons that will go through you and the guy behind you. His rounds go through walls so you can’t barricade on either side of the door. He has a bunch more ammo than you.
Do you go in, and almost certainly get killed and waste the effort or wait for more guys who are bringing flash bangs, rifles and rifle plates?
I am glad that I did not have to make that decision.
So based on what you have read and understand as truth, the officers prevented the terrorist from shooting on helpless citizens for close to 50 minutes?
That is what I want to believe.
Maybe officers need to carry flashbangs...
