People shouldn't complain about Privacy while they at the same time share everything about their life on Social Media.

I had a discussion with a co-worker today. We talked about surveillants. I thought that London and places in Japan did the right thing by installing a bunch of cameras around the cities. It has prevented AND solved a lot of crimes. He didn't agree. He said that he wanted his privacy. He went on and on about the huge privacy issues we have today. Like how the government scans and reads our emails and yada yada. I simply asked him "if privacy is so important to you, how come you share EVERYTHING about your life on social media? You upload photos of yourself, your kids and your wife. You have your house and address online. You share your work and expensive stuff you own. How come you're so concerned about privacy when you're giving 100% away every day?". He didn't have an answer for that at all.

I get that you want privacy regarding money, bank information, and other personal stuff. But other than that, what do you have left to protect by not installing cameras everywhere?
