I'm sorry, but there is absolutely no way you can convince me that a member of the SWAT team took the appropriate action by opening fire as SOON as someone answers the door...
Hell, even in the military, there's a such thing as positive identification, escalation of force, and basically "not shooting at something that isn't trying to harm you"...
Say what you want to defend this scum, but if you can't properly assess the validity of the call (which, I agree, you really can't), you should at least be REQUIRED to assess the presence of an actual threat once you get there...for all they know, in a real hostage situation, the offender could have sent one of the hostages to open the door...
