Well POTUS to the machine gun option off the table. Se we can't shoot them. As for tunnels. Unless citizens are given a real nice bounty for finding them, they will continue. Potus won't let us booby trap them.
Saw a vid of a KFC place that was out of business, but the was a tunnel in it. Was found out because the local cop though to was being robbed.
If shit heads in the USA would stop taking and buying this shit then the money would dry up. But America and it's need to poison it's body with muh drugs. Seriously, just say no.
