This is a scam, hang up and call your DEA, no such person. Call FBI also. They will never call you and threaten you, they just show up. He will say you must pay money or you will be arrested. He will continue to harass, but don't give in. Tell him you are on to his scam. He will swear at you,etc.. David Justice is a fake. Some say he gets names and numbers from online sources,etc. People have actually wired him money. Why would you have to wire money to the DEA or any Federal agency. Especially when he says he is right down the street. Crazy..don't fall for it.
