But I thought he left his wife and drove away

When we see him already 'knocked out' a loud noise happens and his head moves with startled response, like someone awake and flinching.

And if you can find him 'getting knocked unconscious', it looks nothing like what happens in most cases in real life. Kick is weird, no brain reboot seziure (no, it does not have to be long, but often happens in eyes, jaw, wrists or ankles). Wrong head movment to instant trauma (watch a real fight or a foddler taking a hit to the grill). Kick looks delivered away from his face by 3 to 7 inches, at that camera angle.

Also, why were fireworks under his truck, after he fled (and left his wife), with now a mob stopping him for what purpose?

[Cut to] something burning under his work truck, flashing lights of vertigo, sloppy kick to the head and his wife (who teleports) crying, while black clad EMT's(?). Do nothing of susbstance in a situation of mental or physical tests to asses trauma, but look compasionate while a 'black' actor plays the aggressive fool?

I call propganda incitment.
