Headnotes

  1. Criminal Law & Procedure — Fourth Amendment Search and Seizure The conduct of federal agents in having an undercover informant, carrying a concealed radio transmitter, enter a suspect's place of business with consent and record his incriminating statements, which were overheard outside by another agent, does not amount to an unlawful search and seizure under the Fourth Amendment. 343 U.S. 747, 750–753
  2. Criminal Law & Procedure — Fourth Amendment An undercover agent who enters a place of business with consent, and whose subsequent conduct does not render the entry a trespass ab initio, commits no trespass for purposes of the Fourth Amendment. 343 U.S. at 751–753
  3. Criminal Law & Procedure — Trespass Ab Initio The doctrine of trespass ab initio applies only as a rule of liability in civil actions and is not applicable where the right of the Government to make use of evidence in a criminal prosecution is involved. 343 U.S. at 752
  4. Criminal Law & Procedure — Fourth Amendment The contention that an undercover agent's entry was a trespass because consent was obtained by fraud is rejected, as the rationale of the trespass ab initio doctrine rejects such fine-spun doctrines for the exclusion of evidence. 343 U.S. at 752
  5. Criminal Law & Procedure — Fourth Amendment Where an agent stationed outside the premises overhears a conversation inside by means of a radio receiver, he is not a trespasser; only in the case of physical entry by force, by unwilling submission to authority, or without express or implied consent does the trespass problem arise. 343 U.S. at 752–753
  6. Criminal Law & Procedure — Fourth Amendment Decisions relating to problems raised where tangible property is unlawfully seized are inapposite in the field of mechanical or electronic devices designed to overhear or intercept conversation, at least where access to the listening post was not obtained by illegal methods. 343 U.S. at 753
  7. Criminal Law & Procedure — Fourth Amendment The presence of a radio set is not sufficient to bring a case within the reach of wiretapping doctrine; the use of a transmitter and receiver to overhear a conversation is not a violation of the Fourth Amendment, even where the listening post was not obtained by illegal methods. 343 U.S. at 753–754
  8. Communications Law — Federal Communications Act — Section 605 The facts do not show a violation of § 605 of the Federal Communications Act where there was no interference with any communications facility the petitioner possessed or was entitled to use, and the petitioner was not sending messages to anyone or using a system of communications within the Act. 343 U.S. at 754
  9. Criminal Law & Procedure — Exclusion of Evidence — Disciplining Officers Evidence obtained by federal agents who violated no federal law should not be excluded as a means of disciplining law enforcement officers; a violation of state law, even if shown, would not render the evidence obtained inadmissible in federal courts. 343 U.S. at 754–758
  10. Evidence — Admissibility — Credibility The use of informers, accomplices, false friends, or other betrayals may raise serious questions of credibility, and a defendant is entitled to broad latitude to probe credibility by cross-examination and to have the issues submitted to the jury; but such stratagems are regarded as raising issues of credibility, not questions of law warranting exclusion. 343 U.S. at 757–758
