A Kansas City clerk took matters into his own hands yesterday when he fired off shots at two would-be robbers who tried to hold up his Shell gas station, reports KMBC 9 News.

And now, authorities are concerned that the clerk may have gone too far. Security footage shows the man defending himself against the attackers, but he continues to fire off at them even as they fled. Experts say it’s unclear if shooting at someone who runs away counts as a self defense act under law.

The suspects are still at large.

But the real gem from this story comes from the very eccentric witness (READ: Bat shit crazy) who gave an extremely detailed account of what happened.
