Wow,, how did they disable the alarm and cameras? Alarms have backup batteries and electrical boxes have locks.
I don’t know the technical details; they had a lot of practice and knowledge since they were burglars entirely for a living. I think burglaries that sophisticated are somewhat rare, but it’s still best to have insurance and not rely solely on safes and alarms. The 2015 Hatton Garden safe deposit robbery happened even though the robbers did not fully disable the alarm, but the security guard just didn’t bother to go inside and police didn’t come. They planned, timed it right and had insider knowledge, and some theories even suggest it was an inside job. Basically— anything can happen!! My family, and many family friends, have unfortunately had so many bad experiences to believe that a safe/alarm could ever be 100% foolproof. Insurance insurance insurance and don’t put all your eggs in one basket
