Which of the following is generally considered a government agent for Fourth Amendment purposes?

• A. Police Officers
• B. Undercovers, informants
• C. People working at behest/request of gov't
• D. Other gov't employees

Answer: (A)

The key idea is that the Fourth Amendment regulates actions by government actors. Police officers are the prototypical government agents enforcing laws and conducting searches or seizures. When the police act, their conduct is subject to Fourth Amendment scrutiny—requiring warrants or valid exceptions, probable cause, etc.

Informants or undercover workers aren’t automatically government agents. They can be private individuals, and only if the government directs, controls, or significantly participates in their actions are their activities treated as government actions for Fourth Amendment purposes. Likewise, people working at the government’s request may be considered agents only when their actions are effectively controlled or directed by the government. In general, though, the most straightforward and widely applicable example of a government agent for Fourth Amendment purposes is the police officer.
