Therefore, you don’t need a warrant but you need probable cause

A

all speakers assume the risk that the person to whom they are speaking is wired and/or recording the conversation

Q

Difference between an arrest an a detention

A

Differences: - While both are seizure (a person believes he is not free to leave or terminate the encounter because of force or a show of force)

  • Detention requires reasonable suspicion, an arrest requires probable cause (both can be warrantless, except if the arrest doesn’t occur in a public place, then warrant is needed)
  • An arrest requires custody (not free to leave) and also for purposes of criminal investigation or prosecution
55
Q

Knock and Wait and Exclusionary Rule relation

A

When police doesn’t use the know and announce rule, the evidence seized is not affected by the exclusionary rule

Because police with probable cause and a valid warrant are already entitled to an entry and search, violation of the simple knock-and-announce rule has not been deemed grave enough in the federal courts or in most states to justify suppression of the evidence
