I believe that personal privacy is an illusion.
You don't have it, in fact you lost it long ago.
Any person can google you. My real name is listed on a website which tells you what college I graduated from, what day and what topic my senior presentation was on. I can find out where my girlfriend works and where she went to college.
Recently, I have been able to find office numbers of people's names that have been listed in articles that I have read. All I did was google and search through enough webpages. A bank can get tons of information on you past credit history. The government knows your current address, tax information, and probably can figure out how many times you fly.
If you number is listed and I know your name, I can look up your phone number and address.
Amazon can tell you what you have bought and suggest things you might like to read.
So the fact that the LAPD is putting cameras everywhere does not bother me at all. I actually encourage it, because it only removes the illusion and increase security.
They only place you have which is private is inside you head, as long as the government does not make it in there I think that we will be alright.
