New US visa rules will force foreign students to unlock social media profiles

How many foreigners, illegal or not, are committing crimes? And how much could be found out from social media? This seems extremely paranoid.

On the other hand, maybe this will lead to people putting less stuff on social media. This would probably be a net positive.

It's not intended to detect crimes, it's intended to detect pro-Palestinian political sentiment & deny entry to anyone who has posted that way.
