Bugger 'breach of privacy'...
In the cases where police information has been involved, it's much more serious - it''s an OSA matter. Plod stands to go to jail for breach of OSA, journalists stand to go to jail for conspiracy to breach OSA.
I'm surprised this hasn't been discussed more; every plod signs the OSA when they join. A lot of people could be going to jail for a long time over this.
