So it bums you out to see the federal law enforced, but you don't care if it's broken. So is it OK for the federal government to sue Arizona for enforcing the federal law?
Technically, it's enforcing a law to throw someone in jail for years based on minimal possession of marijuana, but I don't agree with that either.
There are methods of enforcement that I simply don't agree with; they aren't consistent with the kind of country I'd like to live in. I absolutely disagree with the way AZ has chosen to handle this issue.
