The subject of illegal immigration is, above all, a matter of law enforcement.
Ultimately, no nation can continue to thrive if its government refuses to enforce its own laws. Liberal “sanctuary cities” such as San Francisco choose to ignore immigration laws. Imagine the outcry if a town in Utah or Montana arbitrarily declared that federal affirmative action or gay marriage laws were null and void within its municipal borders.
If federal immigration law does not apply to foreign nationals, why should building codes, zoning laws, or traffic statutes apply to U.S. citizens?
Who Has To Respect The Laws?
Victor Davis Hanson has some common sense things to say about illmigrants and their relationship with the law and the broader question about lawlessness.
