@ Kevin...A secure border involves a structured / orderly prevention of illicit movement of weapons, drugs, contraband and people at said border. That structure lends itself to a goal and sense of national / local security and US sovereignty. A secure border further promotes lawful entry and exit for properly vetted / processed migrants. Further, a secure border provides for more orderly and lawful trade interactions at ports of entry. Not many of those conditions are occurring right now. Spoken like a good conservative, right?
No not all immigrants are criminals; in fact the actual proportion of criminals among the migrant population is probably less than that similar nefarious proportion for the US Congress ( that may not be a joke..who knows).. But we need to know which migrants are indeed criminals because we know it's occurring; some of them are indeed nutjobs that we don't have need for..and some are indeed dangerous and we have evidence for that. Most aren't but we have to have a system in place to distill / filter / and ID all entering the country. I mean, Disneyland and Vegas casinos do a better job of vetting people than we do at our border currently.
Most of these migrants are attempting to better their life situations and I have no qualms with those people or their intent. Yet we have to have an orderly/ legal / fair processing system to maintain US sovereignty and security; such a system protects migrants as well as US citizens. The costs of the current border situation is another large debacle that's in force; we don't have any idea what it all costs as we pay the tax bill. It's a damned shame that the current system has been broken for so long; delayed asylum decisions, inadequate asylum housing, countless additional inadequacies not the least of which is a quarreling bunch of squirrels in DC ( both / all parties are guilty). It's hard to figure out the largest economic benefactor/s of the porous border ( beyond the drug trade)..that's probably both sides as well in various opaque forms. Money talks and the rest walks...again.
