Major LITERALLY ANY THROWN OBJECT can break plasmaglass windows.

[Lady Birb]

In a recent detective round, one person who I previously brigged for hacking into the armory managed to break a window by repeatedly throwing the brig harmonica at it. I am not even sure if harmonicas even are supposed to do damage to anything, but they can somehow break steel reinforced plasma glass when thrown. This means unless you strip every prisoner stark naked and remove every single item capable of being picked up from the brig, people can still break out. Fix ASAP.
