I have no sympathy, indeed I have a lot of disgust, with people who won't lift a finger to help themselves. They are a huge part of the problem. As long as we have sanctuary cities and local officials who refuse to do their part we will not have the solutions we crave. It is not just a matter of federal jurisdiction, and so what if it were. Why should that stop you from protecting what's yours?
Last year an illegal alien tried to break into my place. I called ICE. They said they don't do detentions based on citizen complaints. What would you suggest, a citizen's arrest? And we do have private group border patrols.
The problem with local police checking immigration status, if they're even allowed, is that gangs will rule the state if everyone here illegally will not talk to police re: crimes.
