Police get stabbed for stupidity

The police in this video paid a very high price for their lack of training and good tactics. Perhaps we can learn something at their expense. Take a look at the video and then tell me if I have missed anything in my list of goofs below.



Here's what I saw:

The cops had no understanding of range or the danger of knives.

The cops placed themselves in each other's line of fire. Oops! Handy way to shoot your partner by mistake.

The cops were not prepared [Side arms still holstered, rifles loosely held]

The attacker was patient and waited until the police got too close. He was smart. He was a predator. The cops were prey and they almost all died.

Did I missing anything?
