-They didn't need to...

They did need to! you dumb fuck, you can't go around detaining people who haven't committed a crime.

There's also no evidence to say he wasn't jogging either so that theory of yours is out.

-They never tried to arrest him...

They just decided to drive up to him with guns to say hello? They used pickup trucks to drive in front of him into making a bypass and into him making a decision, he had no guns on him and they used the term 'citizens arrest' & 'self defense'

Also McMichael used the term fucking n***** So yeah he is a low life fucking redneck.

They also leaked the footage thinking it would help their case! Another reason why they're stupid fucking rednecks.
