There is something fundamentally un-American about arresting people simply because they fall into a category that has an elevated crime rate (in this case, causing an accident).
When I was in High School, we had a cop come in to give a talk about drugs, drinking and driving. He said "50% of all vehicular accidents are caused by drunk drivers." I, being the smart-a$$ that I was (am), raised my hand and said "So you're saying that 50% of all vehicular accidents are caused by sober drivers?" He was not amused.
Let me try to argue by analogy: If we agree that an overwhelmingly disproportionate amount of crime is committed by young African-Americans between the ages of 14-24, should we lock them ALL up to prevent crime?
By the same token, if we agree that an overwhelming majority of vehicular accidents are caused by drunk drivers, should we lock them ALL up?
Punish the crime: If someone gets into an accident while drunk, throw him/her in jail. If he/she kills someone while driving drunk, give 'em the death penality.
Punish the crime, not the fact that someone falls into a category with an elevated risk of a crime happening.
How do you offer that the crime can be established as actual? How do you prove it in order to inflict those punishments?
