Difficult to do when he's your only hate figure still in the game.
With respect, there are countless 'hate figures' who have never been out of the frame or out of the game starting with Madeleine and the rest of the McCann family.
Christian Brueckner is an habitual sex offender who should have been interrogated in 2007 along with the other recorded paedophiles who were there at the time.
Surely it must raise questions as to why the guy whose duty it was to oversee that diligence but omitted to do so; introduced Brueckner to Joe Public as the fall-guy / scapegoat or whatever.
Thereby playing yet another 'get out of jail card' for both prime actors while setting the slavering internet following in their place in the script and direction they should be following.
One simply cannot believe how the forces of law and order are the bad guys and
a serial sex offender is the hero until one becomes acquainted with the denizens inhabiting the hate zones which are the underbelly of the internet where the erstwhile 'Justice for Maddie' crew still lurk perhaps under their new sobriquet of 'Christian is an innocent scapegoat', much as they were told to do.
