I do not know, as I do not reside in Arizona. I do know that border states (I am a Texan) and counties are always at the federal trough for additional Law Enforcement funding. It is a catch-22. The funding for drug interdiction, armored personnel vehicles, surveillance equipment, and automatic weaponry is in the $400 million range. But this gadgetry may only be used against American citizens. The bribery and intimidation within CBP and certain Sheriff departments is blatant and rampant. Corruption abounds on both sides of the border. The Mexican Federal police turn as much of a blind eye as the US government does. The human toll on illegal immigrants, legal immigrants, and American citizens is staggering. Slave wages, forced prostitution, coerced drug mules. The economic impact is huge, especially for healthcare and basic services. It becomes an unfunded federal mandate, due to misplaced priorities. English only? Our school district works to mainstream Spanish-speaking students within 2 years. Fines do not fix the problems. Amnesty did not fix the problem. Mass deportation is untenable. Green cards and gold cards are a farce. A wall is a joke.
Who will bell the cat?
You spelled it all out - the ONLY way to cut this down is to put real teeth into the laws that will punish the American traitors that draw the low-cost labor up here to line their pockets.
