Isn't Seizure a medical term? Like in epileptic seizure? I haven't seen it used in context of police policy before. I always hear confiscate when people mean to take possession of by legal authority, not seizure. Just saying.
Oh, you haven't heard it in that context so it means it is being used incorrectly? At least as far back as the writing of the US Constitution it has been used:
"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."
1. the act or an instance of seizing.
2. the state of being seized.
3. a taking possession of an item, property, or person legally or by force.
4. a sudden attack, as of epilepsy or some other disease.
