It's a sad day when an invading foreign force can't murder a local, film it, download it to his PC and when arrested for another crime in his home country, have to answer for his action?
An army can't expect unqualified support for the actions of every soldier. Nazis are still being hounded. The poor things, it must have been very stressful?
