I wish people would stop making unverified claims like this "Those guys are pretty much animals so simple things like color and sound can likely have a strong influence on them."
Who says they're animals? Which animals punch eachother in the nose all the time? Who says that colors have a stronger influence on prisoners or recidivists than normal sections of the population?
Savaric, I can't take you seriously when you make such powerful assertions without sources. If you can back up these wild opinions then do so in your primary post rather than have people call you on it, thus wasting everyone's time.
