Really? Two hundred robberies over the last five years and they haven't been investigating them? How do they have 300 photos of "marked robbers" if they haven't investigated the crimes?The robberies should have been dealt with earlier - when were committed. Now when this tragic case exploded spectacularly and internationally (thanks to British press) police want to catch all perps of all robberies at once. Well, better late than never.
I think one reason they are investigating this case aggressively is because a murder took place. I don't think that means they haven't investigated the other crimes. Are Greek police really that negligent?
