"First, they came for sex offenders"

An article by David Rittgers from the Cato Institute, discussing potential implications of the recent Comstock decision by SCOTUS.  I don't agree with them often, but here I do--at least with its concern.  Especially of note:

I responded forcefully that such a system is antithetical to American traditions of due process. Battlefield detention is necessary to incapacitate insurgents and terrorists overseas, and is often employed in lieu of killing them. Broad powers of detention without trial in the criminal context do not make Guantanamo less controversial; they bring it on to our shores and in to our courtrooms. If we have enough information to show that someone is a threat by a preponderance of the evidence in order to detain them, we probably have enough to indict them for conspiracy. One of the reasons that few people turn to political violence in the United States is that the Bill of Rights bars the government from telling the citizenry how to worship, what to think, and what they can say. Generally speaking, you have to actually be a criminal to get charged as one.
