It used to be that street photography was, for the most part, only seen by the photography buffs at photo shows and such, and in the occasional photo specialty mag. Now? It can be posted on the internet and seen everywhere. And once facial recognition software is readily available? Ugh. This ready availability is a problem for many people and specifically for people who do not wish abusers/stalkers to recognize them and know where they are. Sometimes a PFA is not enough.
