True, but we have no evidence zimmerman initiated a confrontation, and given that lack of injuries on one side and the presence of injuries on the other, it's highly likely the one who caused the most damage is the initiator.
Even so, if you read self defense legislation, there is almost no way that trayvons reaction was appropriate. Even if zimmerman had grabbed trayvons arm, the response trayvon used in retaliation would still give zimmerman the legal right to shoot him.
2 months ago proles were waiting to hang zimmerman from the highest tree. I am happy that after having multiple holes being punched in the narrative, you have at least adopted a "Wait and see" viewpoint. This is good.
