BBM - I think could make a diff.
IF MB was left handed,
IF MB reached thru window into LEO's vehicle,
IF MB reached for gun in LEO's holster/duty belt,
IF holster was at 2:00 - 3:00 on belt (or approx'ly under his right elbow w arm at side),
THEN seems, imo, MB's leverage & strength in assaulting LEO would be more powerful
than if MB tried same motions - either
-w his left hand, if his dominant hand was right OR
-w his right hand, if dom. hand was right - because of awkward angles, etc.
Ditto, even if door had been open and LEO was turned, partially exiting the car.
Was he ambidexterous, or did he switch hands/arms for diff functions, e.g.
writing w pen, baseball pitching/batting, eating w knife & fork, punching, shooting a firearm.
I don't want to play patty-cake w anyone his size. Well, any size, for that matter.
