I was 90% sure about Nick being involved before but now it seems to me that he 100% was.
For one thing, he either changes or exaggerates aspects of the story at random.
Secondly, he'll say one minute that they've been quiet, when we all know they've done videos saying 'we've got them.'
Thirdly, if they had footage of the faces as they claim, then surely that's case closed?
What really gives it away for me is the way they act. He over-acts and keeps repeating 'you're sick in the head if you think anyone is capable of this.' People are capable of it, it's been done before and will be done again. They both love to say 'i don't understand the mentality...' catchphrase too.
Total frauds and money grabbers in my humble opinion and the only reason they can't be quiet and leave the investigation to take its course is because he's tit scared that people are on to him, so he's over compensating and acting overly angry in panic.
