What I'm saying is why don't the cops ask about the legality of somebody being in the U.S.?
The "war on drugs" is a failed attempt to keep funding the politicians that are involved in smuggling them into the U.S. and to keep us under the PD's (Presidential Directives) that have been keeping us just shy of Martial Law for the last 70 or so years.
What don't you understand about the 2A?
