Once the cops have pinned a non-violent suspect to the ground, how many times are they allowed to punch him in the head? Is it fewer than 20? I would say so, but I'm not a Greenville County, South Carolina, deputy.

Greenville officers approached a man at a Walmart parking lot on Saturday. The man appeared to be under the influence of alcohol or drugs, and didn't respond to police questions or instructions. Eventually, the officers followed the man inside the store, where they attempted to detain him. The deputies claim the man resisted, though video footage of the incident certainly makes said resistance look passive, rather than violent. But once the two cops had the man on the ground, one of them immediately began punching him in the head. I count at least 20 blows.

Onlookers were horrified, and begged the deputies to stop. Many thought the treatment of the man was cruel, according to WSPA.com. "Please don't punch him like that, don't punch him no more," said one witness. (More video footage can be seen here.)

The man was eventually tasered and then taken to the hospital. Police have not given his name or explained what the charges against him are. The department is reviewing the footage, however, to determine whether the deputy acted properly when he punched a helpless man in the head over and over and over again.
