As long as laws exist people will break them. As long as govt exist, there will be a deep state trying to take it over from within. Who declares the wars? Who writes the laws nobody needs? Govt is the problem not the solution.
A wall is not the answer. Ending the free education, free healthcare, free welfare will stop them. Treat them like the criminals they are along with the employers who illegally hire them. News laws and new walls are not the answer, enforcing the laws already on the books is all it takes.
"criminals" are those who dont buy into the govt control system and choose to express their true freedom. Wake up and stop buying into the concept that govt knows what is best for everybody.
As long as the public wants and uses illegal drugs then drugs will come across the border. No wall will stop that.
