I've seen estimates that about 90% of ICE detainees are held in facilities run by private operators (GEO Group, CoreCivic, etc.), and I'd be surprised indeed if it weren't at considerable profit per person.

To anyone not guzzling the Kool-Aid like it came from a firehose, this tells all you need to know about both the quotas and the expansion of this effort far beyond the dangerous criminal portion of illegal immigrants it was pitched to be targeting. Ka-ching!
