A landlord let them in, and that was not enough
The Civil Rights LawyerOutside OhioExplained, not filmed
Officers enter a home without a warrant on the strength of permission from someone other than the person living there. The footage is the clearest illustration of a rule that sounds obvious and is constantly ignored: permission has to come from someone with authority over the space, and a landlord does not have it over a tenant's home.
What it showsChapman and Olson on the page, on camera, and the Payton line quoted on screen: absent valid consent or exigent circumstances, officers may not cross the threshold of a residence without a warrant. The argument afterwards is almost never about whether a landlord can consent. It is about whether the officers reasonably believed the person at the door could.
