The guy was struggling with officers. They were right to use Taser to control the male and prevent being injured. He was pre-warned but continued to be violent.

GOT WHAT HE DESERVED.

His hogging of the microphone was actually infringing on the right to free speech of the others in the room, because he was not giving them the chance to get up and ask their questions.

All the hysterics are fooling you too. People do that when they realize the only way of getting out of the mess they’ve made for themselves is to enlist pity from their audience. In places where tasers are not used, he’d have been pepper sprayed, and in some countries other than the U.S., he might have been SHOT. I am still trying to figure out which one of this little bastard’s "rights" was violated.

This is a quote from a brother in arms,
A Sergeant in Illinois
"I appreciate your point of view however, I would like to clarify a couple of your arguments from a police officers perspective. First, even though he is “still a kid” kids are very capable of hurting and killing others. Look at school shootings (mass murder) over the past ten years should easily convince you of that. Second, you did not see a threat to Senator Kerry but I did. Watch the video again and notice that the student was between the Senator and the police at one point. Meaning he had a clear shot at rushing the podium unabated to the Senators location. The student was obviously emotionally imbalanced and his future behavior could not be predicted by the officers at the scene. Keep in mind during the presidential election, Senator Kerry enjoyed the security and protection of the United States Secret Service. I will not speak on their behalf, but I’m fairly certain in the same situation, the USSS agents would have done the same thing except a lot faster and without apology. Third, of course he has freedom of speech, up into the point he was given a law order which you acknowledge he was issued. Once he was given that lawful order it was his responsibility to comply. He did not and the officers escalated their force by placing hands on him and remove him from the auditorium. Again, the officers did an excellent job. As the student was being escorted up the ramp he pushed back against the officer using his left forearm and hand (review the video). The reason five officers jumped on top of the student was for his safety. The alternative could have been one officer having to escalate his use of force to striking with his hands, using pepper spray or a baton. You do not see any officer take a swing at the student because they had the numbers. Now you will argue something to the effect of “Well if they had the numbers, why did they use the Taser?” I would answer good question and excellent observation. Once the officers were on top of the student he failed to comply with verbal commands and resisted arrest. There were NOT ENOUGH officers there to control the violent actions of the student and the Taser was deployed. You will notice the student was raised to his feet once he was handcuffed and was talking just fine to the officers. He did not have any long term effects from being stunned by the Taser. I know firsthand of the Taser’s effectiveness because I am a certified Taser instructor and have taken a full shot from the taser and was fine moments afterward. The alternative to the Taser would be blunt force trauma like a punch or a strike which could result in a bruise or a broken bone. Your assertion that what you saw looks “hilarious” (which you misspelled by the way) and “takes away the integrity part of being a LEO” is both an uneducated opinion on your part but more importantly, hurtful to the men and women who put themselves in harms way on a daily basis, to protect you and your freedom of speech. Lucky for you police officers have thick skin and are a very forgiving bunch. I hope this clarified our position on this issue…"

Then they arrested him, and he resisted arrest. That’s why he was tasered.

He wasn’t there to ask a question, he was there to disrupt the event.

First, by the overt brutality displayed by the Florida University police. Hopefully, this young man has retained legal counsel and will sue the university and receive a handsome settlement.

Secondly, leading up to the arrest and tazing, the reaction of those chairing the event in trying to quash a perfectly legitimate and well-articulated question by an obviously concerned and passionate student who has come to the right conclusion that there is but 1 degree of separation (or less) between Republicans and Democrats.

But what I found most troubling about the entire video, was accepting at the very end of the incident, when the you man was prone and about to be tazed, not a single person in the room – not one – came to his defense as he was brutalized by these thug-like police. Only AFTER he was tazed did one young woman protest his treatment.

I feel very badly for the future of the US.

He was then being escorted out and tried to break away from the police and inadvertently elbowed and struck two of them in his flailing. At that time they took him to the ground to hand cuff him and he became resistant by not complying with being handcuffed and was tasered after being warned that he would before the Taser was even drawn. He continued to resist and got zapped.

Of course the Spanish language TV news will spin this in a negative view due to the current resolve by the US to limit illegal immigration and strengthen legal immigration requirements.

If I can get a copy of the report, I will post it here. It may not be available for a few days.
