Should smart glasses (Meta Glasses) be banned?

Smart glasses look like ordinary eyewear yet can film and record covertly.

The actor Bill Nighy was recently goaded then filmed whilst sitting outside a London cafe.
The recording was then splashed all over SM.

I once caught a man discreetly filming teenager girls in a shopping centre with his phone, I am pretty sure the pervert has now bought a pair of these glasses, it’s just too easy!

Who needs such technology if it’s not for nefarious practice?

I do not think they should be legal.

AIBU?
