Let's Kill Domestic Spam/Scam Texters

I hate scammers. And I hate spammers. I know, controversial opinion. But seriously, I do think I harbor an outsized rage towards them, at least for someone who's never been a victim of a serious scam (save that one time with Lego).

My understanding is that many of the various scam phone and text operations operate out of organized criminal compounds in southeast Asia, making them relatively impervious to American law enforcement (germane to the aforementioned hatred, I'd mostly-earnestly support orienting our entire foreign policy towards those countries towards finding and decapitating these scam operations).

But some seem to be U.S. based. A few years ago, I alluded to the "jury service" scam call I received, where the caller on the other end of the line claimed to be from the sheriff's office. His accent was decidedly southern-American in character, which I guess doesn't preclude it coming out of a Cambodian compound, but I think more likely suggests the culprit was based somewhere in the United States (it was, I think, a little early for AI-generated deep faking, though of course that's on the horizon). More recently, I've been hit with a flurry of spam texts offering roof repairs; reading up on the angle, it seems that the perpetrators offer a deceptively low rate to "fix your roof", then do intentionally shoddy work while identifying more and more "problems" to try and drain more money out of you. That, too, is a scam which cannot be done entirely remotely, which means the operators have at least some American boots on the ground.

So if there is at least something of a domestic American spam/scam text industry, why does it not seem law enforcement is going after it with any vigor? If I were a DA, I'd answer all those texts and try to arrange meet ups where I'd toss as many people as possible in jail (this is a domain where I am 100% carceral and punitive in character). This seems like such an obvious quality-of-life "win" -- everyone hates these calls -- that any politician or public attorney that was able to really take a high profile crack at it would I think get a ton of positive attention and accolades.
