Thieves attempted a robbery at the same museum in late October but were foiled by the alarm system. This time, the museum's main alarms failed to go off, and the room from where the two paintings were stolen, frames and all, had no alarm, he said.
I guess all you need is to hope that the alarm doesn't go off. You figure if you had a $50 million painting that you would but some kind of personal alarm around that painting.
