Dude, I sympothized with Gambol

Agreed, Gamble's action probably saved the hostage's life but he had to disobey an order and use unconventional tactics. The main reason he was fired was because the hostage could sue SWAT afterwards. I can fully understand Gamble including his outburst in front of the chief. Street and Gamble have to make very hard descisions in milliseconds and other people's lifes depend on it. I am sure they did well in dozens of other situations like this and this time they still managed to save the hostage and yet he is thrown out of SWAT. Sure, disobeying an order and going in although he should have waited is something hard to argue with, then again, sometimes guys like Street and Gamble are better at interpreting the situation than the chiefs and other pencil pushers and paper gangsters.

I see it like this:
If you are the captain of a SWAT team, you should know your guys and how they work, you don't roll dice to determine the members, do you. Gamble must have been known for his attitude and his tendency to override orders if he thinks the situation needs a different approach NOW. If I was the captain of such a team and had someone like Gamble in it, I would be happy that there is someone who can think for himself. But if a captain is too much afraif of loosing his job because his men might cause trouble trying to do the right thing, then this captain should not select people like Gamble for his team. He should search for more people like Street that just play safe and go by book and orders, no matter what.
