Friday's criminal law/procedure cert grants

Issue summary is from ScotusBlog:

• Maryland v. King: Whether the Fourth Amendment allows the states to collect and analyze DNA from people arrested and charged with serious crimes.
• Peugh v. United States: Whether a sentencing court violates the Ex Post Facto Clause by using the U.S. Sentencing Guidelines in effect at the time of sentencing rather than the Guidelines in effect at the time of the offense, if the newer Guidelines create a significant risk that the defendant will receive a longer sentence.
