The computers do it for passports photos at self check kiosks in immigration. The thinking is that the computers are better at it anyways, so no fidelity is lost vs a manned checkpoint. A false negative is easy enough to deal with anyways, and that false positive could have happened at the manned checkpoint as well.

Banned lists are simply impossible to implement in general. Instead, police should be more active in shoplifting and organized theft cases. Someone shoplifts, it’s at least a felony, get them in the system, and apply penalties to repeat offenders. Having stores sort this out themselves is just crazy.
