Today's criminal law/procedure cert grants

The description of the issue is from a post on ScotusBlog, which also links to opinions and cert papers:

• J.D.B. v. North Carolina: Whether the North Carolina Supreme Court was correct in barring consideration of age as a factor in determining when Miranda warnings are required.
• Davis v. United States: Whether the good-faith exception to the exclusionary rule applies to a search authorized by precedent at the time of the search that is subsequently ruled unconstitutional.
• Turner v. Price: 1) Whether an indigent defendant has a constitutional right to appointed counsel at a civil contempt proceeding that results in his incarceration; and 2) whether the Court has jurisdiction to review the decision of the South Carolina Supreme Court.
