I also read that article and wonder how the fuck its possible. Thought all the cash was in secure chests that drop paint on the cash when it gets opened? Yet when if falls on the ground all the money flies out lol...
Depending on the company, one of the ones I know has these safety features
-All the money is kept in airtight bags
-The bags are also put in airtight bags (both these are meant to make sure the bag does not get opened while to its desitnation and money gets taken)
The money gets put inside of a safe in the truck In a secure part of the truck (so a safe in a metal closet)
so thefore: the metal closet would need to be broken open; the safe would need to have been unlocked or broken, and both bags ripped apart for this to happen.
