Yep, and the penalty for possession of marijuana in the District is six months and a $1000 fine. Would everyone be jumping to his defense if he was waving a bag of reefer around? I think not.
Or...what if it was LaPierre who had the magazine? We'd be seeing a different take on things.
If the person waiving around the marijuana did so to support the argument marijuana should be illegal, then those opposed would most definitely point out the hypocrisy.
