Robinson v. Lockhart

How later courts describe this case

• holding that “it is the criminal episodes underlying the convictions, not the dates of conviction, that must be distinct” to trigger enhancement provision
• “[A] federal prisoner cannot raise collaterally any issue litigated and adjudicated on direct appeal from his conviction, absent an intervening change in the law.”
• officer's observation of juvenile shooting a gun in the front yard and officer's observation that the door appeared to have been recently kicked in justified officer's entry without a warrant
