WTF are they scanning for?
"Liverpool's World Museum scanned visitors with facial recognition surveillance"
Surely the value of facial recognition is to identify people you want to be aware of and who you know about. I can see that there is a valid use by public authories for trying to detect wanted/missing/vulnerable persons, (once proper rules have been sorted out), but for a museum?
What database are they comparing visitors to?
Are they worried about either of the Dr's Jones purloining some artefact for the next film in the sequence?
Are the mugshots of John Robie or Sir Charles Lytton loaded onto the system?
Are they worried that frequent visitors will be exposed to a cumulative dose of magic emanating from the exhibits and suddenly find themselves acting like John Hannah surrounded by non-Nestene Autons, so they're building up a database to decline entry after N visits?
