Try reading post 71.
You and everyone else is letting their emotions overrun their common sense.
You are using the exact same logic process as the loony left.
You are taking what’s known after the fact, inserting it into what took place before the fact, and reaching a conclusion.
Before the fact they had no way of knowing anything.
They didn’t know if her intent was to run over people with her car.
They didn’t know she wasn’t armed.
They didn’t know she didn’t have a car bomb.
They didn’t know she had a baby, wouldn’t matter anyway since muslims aren’t above blowing up babies.
They didn’t know she was a mental case.
They knew nothing about her.
Had they let her drive off and she drove into a crowd of people, got out of her car and started shooting before the car exploded killing 50+ people, you and everyone else would be wondering why they didn’t stop her when they had the chance.
