I think it's possible that multispectral imaging may solve the difficulties these systems have with dark skin. However even if this were resolved, I would still oppose these systems because I don't want to live in a panopticon prison society, even if all the technology works correctly and never makes a false accusation. I think such a society is aesthetically disgusting. Furthermore, an accurate system is not the same as a morally just system. A ubiquitous system which recognizes people with 100% accuracy could be used for evil if it ever fell into the wrong hands. Such powerful systems should never be created in the first place, the juice isn't worth the squeeze.
