I was around 50 years ago.
I grew up on the border.
Enforcement was RUTHLESS.
In 1965, in Tucson, you knew who the legal and illegal Mexicans were: the illegals were the ones doing 34 in a 35 mph zone. Because if the cops stopped them, a few minutes later the little green Ford vans showed up and Adios, Guero...you going back to Mexico.
It was after the “civil rights revolution” of the ‘60s that this began to be watered down: La Raza Unida and the other Mexican terrorist organizations started agitating violently to stop the police from enforcing the laws.
This takes us to now, when we have the same people now running the California legislature, working doggedly to undermine and destroy the will of the U.S. to enforce its laws.
All that is happening is they are now confronted by the most formidable force in 5 decades: Donald J. Trump.
The enforcement that he is commanding is about where we were in 1987. When we get back to 1965, the forces of Evil emanating from Mexico City will be in full retreat, terrified that the Big Gringo is finally on to them and not gonna back down.
At at least it was working in Tucson I remember in the 50’s in L.A. the invasion was going on and it got worse every year now the city looks like skid row for the most part.
