A court ruled the FBI needs to get a warrant to inject malware into someone's machine. It can't just set a trap for whoever visits a certain site, without the authority of a court order.

However, the FBI has written new regulations for itself, saying that one court order can authorize it to attack an unlimited set of computers, if they are using Tor.

Senator Widen will try to cut this back.

I think it is legitimate for the state to install spy software in suspects' computers, with a court order; but these orders must be limited in scope so as not to threaten everyone.
