Final answer:
Evidence obtained through illegal means by a private citizen, such as breaking into a home and taking television sets, is likely not admissible in court due to Fourth Amendment protections.
Step-by-step explanation:
The question concerns whether television sets taken from a neighbor's house without permission and found to be stolen can be used as evidence against the neighbor in a trial for receiving stolen goods. This situation brings up issues surrounding legal searches and the admissibility of evidence. The man's actions constitute a break-in and are illegal; regardless of the intent, his evidence collection methods would be considered a violation of the neighbor's Fourth Amendment rights against unlawful search and seizure. Therefore, because the evidence was obtained illegally by a private citizen, it may not be admissible in court.
