The Oxy wasn’t in danger, it’s behind a screen they could never get through. Diapers and booze, maybe candy and electronics would have been vulnerable.
As a pharmacist for more than 30 years, I have been robbed twice. The first thing they want is the money and the second thing they demand is the drugs. Schedule 1 controlled drugs are not all kept under lock and key. Neither are Schedule IV controlled drugs. If that were the case, every pharmacy would need a large room safe on the premises. Xanax, Valium, Librium, Adderall etc.
