Searching employee emails for terrorism

Australia has recently asserted that it is okay for employers to snoop into employee email accounts to look for terrorism.

Poking into employee email accounts will not yield a single legitimate arrest for computer terrorism. Nobody is going to organise an attack like that from their corporate email account unless they are stupid or applying encryption. If they're stupid, they won't accomplish anything anyway, and if they're applying good encryption you won't be able to read it anyway. What it boils down to is a pointless violation of trust.

PS - Basically, you won't find terrorists by their corporate emails.
PPS - And if you seem to find some, they weren't a real threat.
