chased down and murdered an unarmed man..
they chased him down while standing still?
Effectively, yes. They acted to impede his progress; something they had no right to do under Georgia law...
So if you feel like someone is impeding your progress it's okay to punch them in the throat?
If they sandwich me in between 2 vehicles and pull a gun on me after chasing me down several streets for several minutes and hit me with one of their vehicles?
Not only is it ok, it's perfectly legal.
He wasn't sandwiched between two vehicles he had over a hundred yards of free space... you can't block a human being with a vehicle because they can walk around it
the McMichaels weren't chasing him, they were standing their ground in the middle of the street
Nobody pulled a gun on him or aimed a gun at him or threaten him with a gun
this is all imaginary fantasy in a desperate attempt to defend the actions of a mentally retarded Street criminal who attacked two men who were standing their ground
