he was pulled over for driving on a bus lane (not something that is so reckless that it's punishable by death even in the most 'based' countries, in the middle east and things.)
and the running away thing is being questioned, as the passenger just testified. He says police beat the driver, which made him release the brake pedal, so the car creeped forward.
And anyway, police was on the side of the car, so at not point it time they were in danger. And their version of events didn't match the social media footage that has latter emerged.
Justice will take time. but it's hard to see anything but over-reaction and death penalty, as the teen matched the stereotype you described.
