Ich finde den Rant von Cory Doctorow dazu ganz gut (Achtung, angelsächsisch)

In 1994, Bill Clinton signed CALEA into law. The Communications Assistance for Law Enforcement Act requires every US telecommunications network to be designed around facilitating access to law-enforcement wiretaps.

[…]

Telcos weren’t the only opponents of CALEA, of course. Security experts – those who weren’t hoping to cash in on government pork, anyways – warned that there was no way to make a back door that was only useful to the “good guys” but would keep the “bad guys” out.

These experts were – then as now – dismissed as neurotic worriers who simultaneously failed to understand the need to facilitate mass surveillance in order to keep the nation safe, and who lacked appropriate faith in American ingenuity. If we can put a man on the moon, surely we can build a security system that selectively fails when a cop needs it to, but stands up to every crook, bully, corporate snoop and foreign government. In other words: “We have faith in you! NERD HARDER!”
