Pornoscanners head to prisons

Normally technology migrates from prisons to schools to airports — think CCTVs and Pre-Check — but for the late and unlamented radioactive pornoscanners that the TSA had to give up on, the technology path went the other way — if you're lucky enough to be incarcerated in the USA (which incarcerates more people than any other nation on Earth), you may be treated to one or more TSA-surplus pornoscans.
