Except this is allowed in a narrow set of circumstances - to look for missing children. So they can probably dragnet everyone they see to find the missing children or abductors. Now the residents need a way to prevent the police misusing it by sneakily letting it find rapists and murderers.
Welcome to the security vs. privacy debate. Glad to have you here, please read the pamphlet and please don't resort to a "won't anyone think of the children" argument. Because the statistics around facial recognition just don't work for that argument. However many children you think are saved with this: it's nowhere near that figure, if not flat out zero.
