I think Mizer's compiling a report on illegal aliens and wants them deported back to Durkadurkastan so he's collecting evidence to pass to the relevant authorities. Basically the same reason you do it.
TBF be fair to Broon if he'd talked El Alagui up then one of our old signing thieves would have him on a pre contract by now. Either Plymouth or Dundee United.
He'll probably sign for Dundee United to be closer to his family in northern Africa.
