WASHINGTON (Reuters) - U.S. Attorney General Jeff Sessions warned on Thursday that anyone who uses a 3-D printer to make an “undetectable” gun will be prosecuted to the fullest extent of the law, a day after his department asked a court not to block the public from downloading blueprints for the guns.

“We will not stand for the evasion ... of current law and will take action to ensure that individuals who violate the law by making plastic firearms and rendering them undetectable, will be prosecuted to the fullest extent,” Sessions said in his Thursday statement.
