Both the Miranda and Escobedo cases are relatively recent, circa 1968 or so. It would not surprise me if the Big Zero had his justice department go after both.
As long as the 5th stands, both decisions were pretty much redundant and meant for ignorant people to be informed of their rights, IIRC.
Myself, I am sick and tired of ignorant, complacent citizens and believe the mess we are in is largely their fault. That's also why when FReepers post "elections have consequences" kind of grates on me, maybe I just take it the wrong way though.
