Why can't people blur others?

I have never seen not even a single person (other than some in reddit) who blur others the public in their video or pic. People don't get it it's their privacy and U can't picture them without their consent. I hope this attitude of people changes soon. Our mainstream medias also never do it. I've seen in lot of other foreign channel or social medias they blurring out the public. But never in India. I know most people get excited seeing camera Bt not everyone though.

Edit: its against law to take pictur of someone without consent even if its in public i guess most of them dont know.
