Abuse of power

The country's police frequently impose violence on the people and abuse of power is common among US law enforcers, the report said,

Over the past two years, the number of New York police officers under review for garnering too many complaints was up 50 percent.

In major US cities, police stop, question and frisk more than a million people each year, a sharply higher number than just a few years ago.

Prisons in the United State are packed with inmates. About 2.3 million were held in custody of prisons and jails, the equivalent of about one in every 198 persons in the country, according to the report.

From 2000 to 2008, the US prison population increased an average of 1.8 percent annually.

The basic rights of prisoners in the United States are not well-protected. Raping cases of inmates by prison staff members are widely reported, the report said.

According to the US Justice Department, reports of sexual misconduct by prison staff members with inmates in the country's 93 federal prison sites doubled over the past eight years.

According to a federal survey of more than 63,000 federal and state inmates, 4.5 percent reported being sexually abused at least once during the previous 12 months.
