Guys, if you ever find yourself being chased by a bunch of angry men with guns while running across the roof of a building, this maneuver might come in handy. Seriously, because instead of the bad guys shooting you on the roof, they’ll stand on that roof and fire a shitstorm of bullets down on your ass will you crap your pants wondering if you’re in the Matrix.
Honestly though, my best advice is that these guys should try this from a higher building. Preferably at least 10 stories high.
