Interesting Supreme Court ruling on Miranda. HOWES, WARDEN v. FIELDS, Argued October 4, 2011Decided February 21, 2012 No. 10680. Basically the ruling is, a person who is in prison, and who is being interviewed for a previous crime, need not be Mirandized as they are, for the purposes of Miranda, not in custody! You have to read the whole thing as I find it a truly bizarre ruling, not that Im against it mind you.
