I was listening to this yesterday (been a bit busy, sorry I am late) and was reminded about the attitude MAPs seem to have. That they are not pedophiles, they don't like young children, kids, they like young teens. Apparently that is different, quite alright and is only illegal because, erm, well, society and all that!
Working from that perspective he was saying "I am MAP, this was a minor I was talking to. My business, piss off"
Which tells you just how deeply entrenched the MAP view of what they do is!
Then there are the vigilantes who are, in person, face to face, usually quite deeply unlikeable. Aggressive, determined and take no prisoners kind of people. I have the misfortune to share a small town with 2 of them, they are the same as those you see on television, Misfits with A Cause! Not the brightest of sparks and often spouting quite vile insinuations based on their own weird interpretations of normal life.
In short, they are dangerous when given a platform!
I am grimly interested in how this plays out. Vigilante groups reactions will be 'interesting' to see! But good, the law wasn't such A Ass yesterday!
