The same vulnerabilities that enable crime in the first place also give law enforcement a way to wiretap — when they have a narrowly targeted warrant and can’t get what they’re after some other way. The very reasons why we have Patch Tuesday followed by Exploit Wednesday, why opening e-mail attachments feels like Russian roulette, and why anti-virus software and firewalls aren’t enough to keep us safe online provide the very backdoors the FBI wants.
