It seems to me utterly unrealistic that the police actually upholds this law. It never, ever happens that a complaint is correctly fired within 30 days and these images are occasionally reported to be used. The "griffie" is not involved until there is an actual complaint, so those images or data from them is no way deposited there. Furthermore, any action at the griffie will inform the accused, which the police doesn't want to happen in almost any case until they're ready.

This may be law, but it's ignored by law enforcement. I guarantee it. This is totally unrealistic.
