It looked like a put-up job. A fake.
For one thing, the "dead" guy wasn't even bleeding.
For another, there weren't any muzzle flashes.
Maybe they were making a movie.
But were I the guy driving the white car, and had it been real, there would've been crushed motorbikes and run-over gunmen, as I got the car out of there — maybe even in reverse, since the alley from which the white car came was completely clear.
