Fight on medical MJ and guns

Oregon's resident pot guru (what, we only have one?), Lee Berger, is fighting the good fight on whether or not having a medical marijuana card prevents you from also having a concealed carry permit.  Interestingly, the Oregon Department of Justice is on his side on this one, as Jackson County's position, that having the medical MJ card makes a personal criminal for the purposes of the concealed carry statute is pretty hard to defend.
