Freeze or I'll Stomp You!

I'm not sure what this person was being apprehended for, but it sure seems to me that he did not need three policemen to kick him while he was down.

Is the standard operation in bringing down a criminal today to taze them, beat them, then cuff them? How often does something like this happen?

This also does not give me confidence in relinquishing my Second Amendment right leaving firearms only in the hands of the military and law enforcement. Seeing this does not make me feel safer in a world where only policemen have firearms.

 "Whereas civil-rulers, not having their duty to the people duly before them, may attempt to tyrannize, and as military forces, which must be occasionally raised to defend our country, might pervert their power to the injury of their fellow citizens, the people are confirmed by the article in their right to keep and bear their private arms." 

-- Tench Coxe, in Remarks on the First Part of the Amendments to the Federal Constitution. 

"Certainly one of the chief guarantees of freedom under any government, no matter how popular and respected, is the right of citizens to keep and bear arms ... The right of citizens to bear arms is just one guarantee against arbitrary government, one more safeguard, against the tyranny which now appears remote in America but which historically has proven to be always possible." 

-- Hubert H. Humphrey, Senator, Vice President, 22 October 1959.
