After Florida v. Jardines, 569 U.S. 1 (2013), and Collins v. Virginia, 138 S.Ct. 1663 (2018), it is unclear - and there is a split in authority on - whether the Fourth Amendment prohibits police officers from engaging in knock-and-talks to gather evidence, and if officers are allowed to stop and look at evidence of a crime that is nearby and in plain view when they approach a house.

Is an officer's subjective intent still irrelevant to the lawfulness of entry on to impliedly open curtilage?

Once on curtilage can an officer inspect, without touching, what is in plain view?
