When No Warrant Is Needed
The exceptions, and how far each one reaches
The warrant rule has exceptions, and each one is narrower than it sounds. They are not a general permission slip, and a court will later ask whether the facts actually fit the exception the officers relied on.
- Consent, from you or from someone with authority over the place, and only as wide as the consent given.
- Emergency aid, to help someone believed to be hurt or in danger.
- Hot pursuit of a fleeing suspect.
- Preventing the destruction of evidence, where officers reasonably believe it is happening.
- Plain view, of something obviously incriminating seen from a place they are lawfully allowed to be.
Police can create the urgency themselves. Where officers knock, announce, and then hear what sounds like evidence being destroyed, the resulting entry can be lawful even though their own knock caused the scramble. That surprises people, and it is why what happens in the first few seconds at a door matters.
“I do not consent to a search of my home.”
An entry that turns out to be unlawful is challenged later through a motion to suppress, not settled in the doorway.
