Verne Troyer -- Shoots Taser Incident at LAX

Verne Troyer turned vigilante at LAX -- chasing down a man who burst through a TSA checkpoint until police captured and tased him ... and Verne recorded the whole thing.

Verne was on his way to catch a flight to Ohio when he heard the commotion near TSA, and when he saw the suspect running away ... he fired up his motorized scooter and tracked down the guy.

You might call the video ... VerneVision ... it's all shot from his, umm ... lower perspective, but it's awesome, and remarkably steady.

Luckily, police caught up to the suspect before Verne did, but deputy Troyer did manage to capture the moment when officers busted out their Taser and took the man into custody.

Only bummer -- the stupid stairs and escalator that prevented Verne from nabbing the guy himself. He did get a souvenir though -- the straw hat the suspect dropped right before he got zapped.
