Even if the right changed, the main actual causes of police caution would remain:

- a land border with a large continent that has a lot of guns and violence and criminality

- millions and millions of existing guns, the criminal holdings of which would not decrease following a change in the law

- subcultures that glorify violence and teach it as a path in life, particularly how to be a man and what sort of man to be attracted to

> a land border with a large continent that has a lot of guns and violence and criminality

That's a curious perception indeed, given that guns predominantly flow from the US to Mexico and not the other way around, and guns in Mexico are of mostly US origin.

Unclear which side you are talking about.
