New MP for Glasgow East John Mason debated, among other things, the issue of ID cards with Dunfermline by-election victor Willie Rennie and Aberdeen South MP Anne Begg on Scotland at Ten.
He and Willie were obviously on the same side. Now, there are very many reasons to oppose ID cards and the biometric information they hold. Put simply, they are an expensive, ineffective waste of time. It's an easy case to make.
I am told that the argument advanced by John Mason was that they might be prone to forgery by the unscrupulous cutting people's eyeballs out to get round the iris scan. This certainly did happen in a Dan Brown novel once.
Mind you the ability to separate reality and fantasy has never been particularly valued in the SNP.
