So, if I was 20, trying to buy alcohol, with no ID, then actually got it, whose fault would it be? Mine for not having ID and buying illegally, or the vendor who sold it to me, or perhaps the police for picking me up for getting drunk and caught? Just curious since it might tell me more about a person's thought processes. Thanks and keep up the good work defending us!

In your senerio, the vender would be at fault for selling you the alchol, and if you were aprehended, you would be a minor in possession of alchol. I'm not advocating that not having an ID is a crime or should be law, but the majority of people without ID are probable concealing some sort of illegal activity.
