Security cameras : why are people against them?

[MODU]

I have no problems with security cameras.  They aren't an invasion of privacy in my book, especially since they are erected in public.

I think the majority of people would change their minds if a crime was commited and they caught the guy/girl who did it through surveillance.

That is why stores and airports already have their own cameras.  They catch their crooks, and no one in those areas seem to care.   If people have problems with camera's on the street, I hope they don't fly or shop.
