At present it doesn't bother me ....yet.
A vast majority of security cameras are privately owned (security for stores, banks, etc.)
Seems to keep costs down to deter shoplifting, or help catch major criminals (kidnappers, bank robbers, rapists, etc.).
The moment the goverment operates and links the cameras to a central unit to monitor law-abiding citizens to prevent them from exercising their First Amendment rights, then I'll have a problem with it.
