JeremyL is correct
.. even still if the average person hit Dvon him striking back wouldnt be self defense...thats called "instigating premeditated violence" since the simple fact is he wasnt try to protect himself.
likei said , at the stop light ,him coming out of his car and up to the other guy in the streets trying to start a confrontation ( AGAIN and occured a WHILE later) or in other words "baiting".
Suppose for the sake of convo the dude whipped his ass -- i dont think the judge would give him justification regardless.
