If someone has a drink and then is responsible for an auto accident, that person should be held accountable because someone's rights were violated. Having a glass of wine at dinner and then driving home infringes on no one's rights.
DUI, drug and prostitution laws are all analogous to gun laws. They all aim to prevent a potential crime or violation of rights. The problem is that there is no victim.
I tend to believe that this form of “justice” fosters a disrespect for the law overall. There should be an inherent understanding that the violation is wrong. Owning a gun peacefully is not wrong. Using a gun to commit a crime is wrong. Stepping outside this framework breeds not only a disrespect for, but also a distrust of the law and those that enforce it.
Liberty and individual responsibility go hand in hand.
The rest of us say that DUI presents an unacceptable risk threat. If DUI is 'victimless', then firing a gun into a crowd is also victimless if the bullet happens to miss everyone.
More true words were never spoken.
