I came to this assuming he was guilty, after all why would they make an arrest so long after the crime if they weren't sure? However, the prosecution case has convinced me that Richard Allen is innocent. More importantly, even if he was guilty, they haven't proved this at all.
His confessions are tainted by the prison psychologist being active in online communities discussing the case and sharing this info with RA. This means unless it's possible to prove there was no mention of a van anywhere online in relation to this crime, there has to be reasonable doubt about where he got the information from. Of course, the defence appear to have some information that Weber's van wasn't there anyway...
I'm not sure why people think the change in height on the fishing licences is suspicious. The most likely explanation is that the form was filled in one year by RA and the other by his wife, as they shared both the computer and fishing licence. RA wouldn't be the first short man to add a bit to his height.
I also don't understand the inclusion of the bullet evidence. Even if it were possible to definitively link the bullet to RA (it's not) there's no proof it's linked to the crime. It's a common calibre bullet found on the ground in an area known for hunting. Maybe it is connected, but there's no way to prove this.
I've been truly shocked at the sheer amount of incompetence and unethical behaviour in this case. It's so disrespectful to Abby and Libby and their families.
