ARREST AND DETAINMENT

A phone notification can be used as evidence if no further manipulation of the phone was required. A visible phone notification, has no reasonable expectation of privacy.

The supreme court held that the 2nd amendment extends to stun guns/tasers.

Police cannot search a phone without a search warrant unless exigent circumstances are present.

Police cannot arrest a passenger in a vehicle simply because they refused to show identification when the officer had no reasonable suspicion to suspect they had committed a crime.

Police can search the internal phone records and text messages on a cell phone seized from a person during a lawful arrest if exigent circumstances are present.

An search warrant is needed to arrest someone from the home of a third-party.

The doorway of a residence is considered a public place according to the 4th amendment. This means, if you observe a suspect in their doorway and you give chase, the "hot pursuit" exception applies so an officer may follow the suspect into their home to arrest them.

"A police officer can conduct a search incident to arrest that can go beyond just a pat frisk. The search is also not restricted by the nature of the offense."

What this means is, anytime you arrest someone, no matter the reason for the arrest, you may search them beyond a frisk.
