Which is a type of intrusion?

• A. Auditory: Government listens to conversations with or without enhancement
• B. Open field
• C. Visual: Government looks with enhancement tools
• D. Physical: government enters

Answer: (D)

Intrusion involves invading someone's privacy by entering a space where they have a reasonable expectation of privacy. The clearest form is physically entering someone’s private space. When the government enters, it directly breaches that boundary and constitutes an intrusive action. Auditory or visual surveillance can invade privacy as well, but they do not involve an actual physical entrance into the private domain. Open fields typically aren’t protected as a privacy intrusion, since there’s generally no reasonable expectation of privacy there.
