Cornell law professor Sherry F. Colb comments on a case currently before the U.S. Supreme Court that presents the question whether the exigent circumstances exception to the warrant requirement applies when the suspect may have committed a misdemeanor, as opposed to a more serious crime. Colb argues that if the Court believes that a misdemeanor (or a particular misdemeanor) is not important enough to justify the invasion of a person’s home, then it ought perhaps to hold that the police officer in the present should not have entered the suspect’s home, period, with or without a warrant.
