As reported on tuesday's show, what kind of vehicles are increasingly being used to smuggle prison contraband, causing problems for prison officials worldwide?

Drones are the vehicles causing problems for prison around the globe. With just a little coordination from the outside scheduling the time and location of the drop, inmates would be able to snuck in contrabands. The inmate would  ensure the drop is unknown by officers by surveillance, therefore the inmate is in constant contact with the outside drone operator. Lots of officials had address this problem, prohibiting a certain distance from the prison perimeter to fly a drone and clearing to provide a visible path to easily spot anyone breaking the rules.
