That clip cuts out a lot of what happened. These two videos show much more:





I counted, he was asked 5 times to get to his question, which he never really did. Even when he did have a sentence that ended in a question, he didn't stop to hear John Kerry's reply. That's why he was cut off, because he was just preaching, not asking a question.

A normal Q&A session is like this:



As you can see, the person doesn't go on ranting and preaching. They ask their question, listen to the reply and move on.

When they cut his mic off, they first just tried escorting him outside. They didn't have cuffs out and seemed to have no intentions of arresting him at that moment. However, then he resisted. He pushed the officers and resisted as much as he could. The officers had no better solution, it was either let him rant all day when people were there to listen to someone else, or they could use some other force to get him out. So what would've been better? Hitting him with a baton?

If you think that the officers overreacted, then you're just looking at as if he asked normal question and got tased, but that's not what happened. All he would've had to do is ask and listen, but he never did.

And if you still disagree, then consider that Andrew Meyer (the victim) himself has since agreed that he was out of line and that the officers were doing their job. He says that in this interview:



Yes, I've discussed this before :p
