DWI is a crime because there is a well proven propensity for drunk drivers to cause accidents and kill people, far beyond what sober people do.
Would you let a very drunk person walk down the street waving a loaded gun around.
A 4400 pound car is a lot more deadly than a .44 magnum.
Driver fatigue is also deadly.
“It’s rather difficult to arrest him in the half second he needs to weave across the road and kill everyone.”
I don’t know what sense this makes. It’s tough to stop a lot of crimes in the time it takes to commit them, but that doesn’t mean we arrest someone because “they seem like the type that will rob a bank”, for example.
“DWI is a crime because there is a well proven propensity for drunk drivers to cause accidents and kill people, far beyond what sober people do.”
Like I said, it’s “pre-crime”. You think someone is likely to commit an actual crime (infringing on the rights/life/property of others), so you are arresting them in advance.
“Would you let a very drunk person walk down the street waving a loaded gun around.”
No, because brandishing a weapon is already an actual crime. If they just had it holstered, which would be more analogous to driving over the legal limit but not violating the rules of the road, then yes, I have no problem with that.
