Summary

Byron White New York v. Harris — Opinion of the Court

To put the matter another way, suppressing the statement taken outside the house would not serve the purpose of the rule that made Harris' in-house arrest illegal. The warrant requirement for an arrest in the home is imposed to protect the home, and anything incriminating the police gathered from arresting Harris in his home, rather than elsewhere, has been excluded, as it should have been; the purpose of the rule has thereby been vindicated. We are not required by the Constitution to go further and suppress statements later made by Harris in order to deter police from violating Payton.

Byron White New York v. Harris — Opinion of the Court

Even though we decline to suppress statements made outside the home following a Payton violation, the principal incentive to obey Payton still obtains: the police know that a warrantless entry will lead to the suppression of any evidence found, or statements taken, inside the home. If we did suppress statements like Harris', moreover, the incremental deterrent value would be minimal. Given that the police have probable cause to arrest a suspect in Harris' position, they need not violate Payton in order to interrogate the suspect.
