AFAIK there isn't currently any surveillance on search - searching for how to make a bomb does not lead to police at your doorstep the next day. But the police raid after a mass shooting generally brings up plenty of similar searches.

Maybe it could be good to have some integrations between this data and law enforcement to reduce leading to tragedy? Maybe start not with crime but suicide - I think a search result telling you to call this number if you are feeling bad saves far less lives than a feed into social workers potentially could.

Just a thought, and this isn't have a computer sentence someone to prison but providing data to people to in the end make informed decisions to try to prevent tragedy. Privacy is important to a degree but treating it as absolute seems to waste potential to save lives.
