Hard to say if it'll just be the local sheriff. We're going through massively transforming times. The local sheriff makes sense in a 1950's idyllic small town when your local bank was local, when most of the businesses were local mom&pops, when most things you owned were made in America, etc.
But given the sheer amount of off-shoring and privatising, the Chinese making most everything in the Big Box, reliance on Blackwater abroad, and globalized corporations+banks, I'd think that an economic collapse mass foreclosure scenario will eventually pan out differently. In the years ahead, I see private security companies and armies, traded on the global market, maybe alot of them Chinese, doing most of the evicting.
