“The driver of the tractor trailer did exit the vehicle and walk toward a black Nissan. The driver of the Nissan got out,” said Miami-Dade police spokesman Alvaro Zabaleta. “There was a physical confrontation between both of them. We’re being told the driver of the tractor trailer was armed with a knife during the confrontation and that’s when the driver of Nissan produced a firearm and shot the victim in this case.”
Obviously this just happened and more info will come, but knowing how stingy with info MDPD can be, I think they pretty much have decided that this is a case of Self-Defense. So, short of the shooter being a prohibited person or other details we do not know, this seems to be a straight-forward but sad defensive event.
