Last night in Berkeley, Mo., protest erupted after 18-year-old Antonio Martin was shot and killed by police after reportedly pulling a gun on an officer.

A Twitter user claimed to have witnessed the shooting of his “best friend”:

The Huffington Post interviewed this person in a Twitter conversation, and they were told that Martin was unarmed and shot for refusing to get down on the ground, which they initially reported. Just one problem — the “witness” wasn’t even there:

By then the bogus version was already “out there” and will probably live on for a while.

A message to HuffPo from their original “source”:

Real journalism.
