Surveillance video caught the second thieves broke into a gun store in California.
Crooks rammed the front door open, then two of them with masks ran through the broken glass.
They tried to break down every door, from the office to the bathroom.
They even used a hammer!
The suspects left empty-handed, but they weren't done.
They tried to rob another gun store just 2 miles down the road, but they couldn't get to the guns in that store either.
Police are still looking for the suspects.
