Stanley v. United States

“perfunctory and undeveloped arguments, and arguments that are unsupported by pertinent authority, are waived” | trial judge erred in departing downward because of disparity in sentence between defendants who engaged in similar conduct but were charged with different offenses as result of prosecutor’s plea bargaining decisions | no unwarranted disparity resulted from prosecutor’s plea bargaining practices that resulted in defendants who had engaged in similar conduct being charged with different offenses | where officer has legal right to be on premises, he may seize evidence of a crime or contraband, the criminal nature of which is immediately apparent, which is in plain view
