The Pesudo-Collectivist theory which states that if someone commits worng, then all must be punished as a result of that individual's wrongdoing.
Universal Punishment includes:
Gun Control: One out of 80million gun-owning persons just went off the deep end and murdured his family, so let's take away everyone's guns.
War On Drugs: One out of God knows how many coke sniffers just flipped out and killed a kid with a baseball bat, so lets ban ALL drugs.
These Gun and Drug control laws will be sure to lower the rate of shootings and drug overdoses in this country to 0%. After all, it's not like there's a black market where people could get them, or anything...
