I'm trying to follow Madeleine's line of thinking.
If you believed a random attacker did it, then you have every right to be irritated at CPD for not following up leads. But there's no point in going on and on about someone hacking Brad to frame him.
If you believe some Nancy knew did it, then you're correct to be all off down the trail of who-hacked-Brad, but the CPD following up on leads to do with random attackers in vans is something that shouldn't concern you in the slightest.
So: random attacker people, don't concern yourselves with hacking theories because it makes no sense.
So: Nancy's boyfriend people, stop grumping about CPD not contacting every single tipster personally to assure them that the info they already had was, er, re-had.
Yes?
