Black man # 1 incorrectly thinks the 2nd Amendment is all about providing the opportunity to go hunting and shooting and, more importantly, that weapons such as AK-47s should only be in the hands of soldiers and not criminals (one has to wonder if citizens are then equated with criminals?).
Black man # 2 correctly notes that the 2nd Amendment is all about being the citizen's last defense against tyranny (and, that would tend to equate citizens as soldiers).
The sorry thing is, black man # 1 is supposed to be a constitutional professor.
Bonus Footnote: Watch Suzanna Hupp school Texas Legislators on the 2nd Amendment.
UPDATE: Should probably note that if Obama is so concerned about AK-47s getting into the hands of criminals, then perhaps he should take the Fast & Furious scandal a bit more seriously.
