As already known, white policemen in Missouri State shot to death two guiltless young black men in August and October this year

On November 22, a 12-year-old black boy playing with toy gun was shot to death by a white policeman in Cleveland City of Ohio State.

The facts give a glimpse of the true picture of the U.S. police that does not hesitate to fire bullets at innocent citizens under pretext of "self-defense".

Such killings by the police are an accepted custom in the U.S. According to data released by the Amnesty International, at least 500 people were killed by the police's shockers in the country from 2001 to February 2012 and 90 percent of those victims were barehanded.

However, such police murderers remain unpunished and, on the contrary, are defended by the government.

After all, the killing of people by the police is an inevitable product of the U.S. social system, which legally defends murders under the signboard of freedom and democracy.

The U.S. talks much about "defense of human rights", but it can never cover up its nature as the worst human rights violator.
