Lyric discussion by piperatthewall 

the mental health system is a disgrace. give the crazy people some medication to shut them up, and just hide the problem. what the staff does not realize, is that they are only covering up the physical symptoms. have a hole in the wall? put a picture frame over it. roger waters seems to share my view on this, portraying the faults of this system with his ever present angst and sarcasm. way to go roger!

There's a reason it's called "behavioral medicine." All it does is slow you down physically, physiologically, and in turn, mentally. I guess the idea might be that if you slow down their brain enough, they might be able to come to grips with it and be able to catch yourself a little before you say or do something "insane." By the way, the word insane is not a medical term, it's a legal term. Someone who is insane has perpetrated a crime of some sort, while someone who is just mentally ill may not have.
