Ashcroft is only enforcing the law on controlled substances, by reversing Reno's exemption for one state to use them in killing. If the federal law is going to have meaning, he had to reverse her single exception. The DOJ can't say to CA that docs can't prescribe pot, but Oregon can prescribe lethal injections. It doesn't make sense. The DOJ will prevail in this case - on the basis of the law. And when it does - people in Oregon can still off themselves by whatever means they can get their hands on themselves.
