I don't see much problem from the video itself. Without knowing the circumstances leading up to the kicking in of the door can't really say much. If they had probable cause due to a call of domestic violence (which is what it sounds like) they should kick in the door. Then the rest plays out like it does for any idiot that refuses to obey an officer when they tell you to lay down and put your hands behind your back. It ends with a rough arrest and your ass going to jail most likely.
Couple of things though, that website states the woman was tazed first. I believe that to be false. You hear the first taser shoot and see the wire from the one pointed at the guy holding the camera. Then as he is crying like a girl you hear the second shot. I still am only assuming the wife got zapped that time because I don't see it but I do hear her starting to scream.
Secondly, you can't see what the woman is doing after the first shot goes off (or even really before the first shot). So you have no idea from that video what happened with the woman.
I will stipulate that if no one made a call or anything like that and they just showed up at their door for no other reason then to just show up they should be in trouble.
