Which of the following is a seizure of personal property that does not require justification under the 4th Amendment?

The seizure of contraband does not require justification under the Fourth Amendment because contraband is defined as property that is illegal to possess, such as drugs or stolen goods. The government has a compelling interest in enforcing laws that prohibit the possession of such items, allowing law enforcement to seize them without needing probable cause or a warrant. This principle is grounded in the idea that society has an interest in preventing the harm that contraband can cause, making it unnecessary to meet the usual standards of justification for seizure.

In contrast, personal belongings, non-abandoned property, and items stored in a vehicle generally require a greater level of justification due to the individual's reasonable expectation of privacy. The seizure of these types of property typically involves the need for probable cause or a warrant, as doing so without justification would violate the individual's Fourth Amendment rights.
