Read the article. My solution, if it doesn’t or isn’t working then mine it. I’m serious. It’s our border, cross illegally and risk death. I’ve got no problem with that.
The same problems are going to exists with mines. Are you going to confiscate people’s property through eminent domain in order to have mine field???
Are going to mine the Rio Grande?? What happens when a mine floats away and kills a US citizen??
