> The [Fourth] amendment is meant to protect Americans from unreasonable searches or seizures of their property by the government.

Much more than that! It reads:

> The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.

Seizure includes, for the sake of example, physical violence and, more specifically, shooting people in the head.
