Seems to me that some liberal usage of chemical booby traps in the safe would be good. Like dye bombs or silver nitrate sprays. Luckily for me I keep my big stuff in a commercial vault. I only have a few oddities at home. I hope the police really put some effort into this. It reeks of some sort of organisation though the amounts they are stealing won't make anyone rich. It seems clear that it is someone watching this forum who maybe sells things and gets people's home addresses.
