BTS--What he said at the article you linked to and what he is saying now don't seem to be different to me. Maybe you don't like the policy, I don't know, but liar??
from your link:
Obama trotted out his standard policy stance, that he had a deep respect for the “traditions of gun ownership” but favored measures in big cities to keep guns out of the hands of “gang bangers and drug dealers’’ in big cities “who already have them and are shooting people...I see a couple of sportsmen back there. I’m not going to take away your guns.’’
whitehouse.gov, under the Urban Policy section:
Address Gun Violence in Cities: Obama and Biden would repeal the Tiahrt Amendment, which restricts the ability of local law enforcement to access important gun trace information, and give police officers across the nation the tools they need to solve gun crimes and fight the illegal arms trade. Obama and Biden also favor commonsense measures that respect the Second Amendment rights of gun owners, while keeping guns away from children and from criminals. They support closing the gun show loophole and making guns in this country childproof. They also support making the expired federal Assault Weapons Ban permanent.
