I was really thinking in biometry as used in a more ordinary situation, like a laptop fingerprint reader. With the most likely form of malicious behavior here being that of identity theft by a small-time attacker. Having to dodge biometric sensors or trying to avoid having your photograph taken at protest are more an issue of surveillance, either by government or by private citizens. Sorry for not making myself clear at first, but what I mean is that passwords aren't a sufficient guarantee of intent either. If anyone has access to them, they can spoof someone's identity. I reckon that this doesn't really fit a civil rights discussion, because we haven't (I think) reached such a point yet, but government-backed attacker might spoof someone's identity in order to either infiltrate or hijack a civil organization. Essentially, a virtual mole.
