This is the very definition of swift justice.
Watch this guy with obvious anger issues receive almost instant karma after throwing a punch at a driver that we assume performed a manoeuvre he wasn't overly happy about. Neither his white Suzuki or the black Jetta appear damaged on a rain-soaked street somewhere in Vancouver, BC, so the reason for the assault is a little puzzling. Unfortunately for the 26-year-old attacker, but extremely handy for the victim, a police van just happened to be on the other side of the divide at the time of the altercation.
So it took just three minutes from when the punch was thrown through the open window to being lead away in cuffs. That's some swift justice right there.
