The weapon in the trunk is clearly not a Bushmaster. You can see the LEO actuating the slide on the right side of the weapon. A Bushmaster has a T-handle at the rear. It looks like a semi-auto shotgun of some sort.

I recall video of the police opening his trunk and taking out a long gun — but it was during daylight — not nighttime as it is here.
