Except when they're out in public with no expectation of privacy then they have forfeited their right to privacy and to not be photographed.
Don't want to be photographed while wearing something like that out in public? Sadly the only actual answer is to wear something different.
Stalking is illegal. Harassing is illegal. Taking a photo of someone as they walk by? Not illegal, nor should it ever be.
Which, as stated before, is a double edged sword. Is it right for someone that gets off on kids to be able to photograph kids playing on a playground? Most people with a moral compass pointing in the right direction will agree that it's not. Is it legal? As long as they're not breaking any kind of restraining order or shooting where they're legally not allowed to.
The thing is, we have to live with possibilities like that to be able to have the freedom to go out and do things like street photography or we'll end up like other countries where it is illegal to do so. So what would you rather have? Protection against this scenario with it being illegal to photograph people in public without their explicit consent or the possibility that someone will be using photos they legally take for some devious purpose so you can go out and have the freedom to photograph people in public places?
