Use Those Handcuffs for Manifestly Appropriate Purposes Only, Please:

From the New Jersey Code, §§ 2C-39.3(k), 2C-39.9.2:

Any person who knowingly has in his possession handcuffs [defined as "a device, conventionally used for law enforcement purposes, that can be tightened and locked about the wrists for the purpose of restraining a person's movement"] under circumstances not manifestly appropriate for such lawful uses as handcuffs may have, is guilty of a disorderly persons offense.

You can guess what my question is.
