Americans mostly in favor of facial recognition at public events: poll (Biometrics Update)
From the report, 59% oppose email and cell phone surveillance (up 13% from 2006), but 79% are in favor of using facial recognition at various locations and public events and 81% support expanded camera surveillance on streets and in public places.
The public probably senses that there are a lot of ways to deploy facial recognition that are much less invasive of privacy than snooping on emails and hacking cell phones.
