So the police were duped in to getting the wrong guy. It’s hard to imaging the position that they are in, as much as there are people trying to help them. They are really on their own, there is no real way for them to use a file some guy posted to paste bin as evidence. It’s junk, you can’t prove where it came from or even who.
So they can really only work on direct evidence that they can prove, and then sometimes at the end of the day you arrest a kid in the UK that speaks on video with a Swedish accent.
