From the Courier-Mail:

A man who established a sophisticated network of peepholes and cameras to spy on his flatmates has escaped a jail sentence after police were unable to crack an encryption code on his home computer.

[…]

They found a series of holes drilled in to walls and ceilings throughout the Surfers Paradise apartment with wires leading back to Wyllie’s bedroom.

Police seized his personal computer, but files were encrypted and a video camera was not plugged in.

[…]

In passing sentence, Judge Devereaux took in to account the 33 days Wyllie had spent in custody after being arrested and ordered that two years’ probation was sufficient punishment, given that there was no hard evidence proving he had secretly recorded his flatmates.
