What does extort mean?

It refers to the appropriation of someone else's property (money or other material) through the use of threats or violence. According to the Oxford Guide "American Law," extortion is a property crime under "theft".

One distinction between extortion and coercion is that property is sought or obtained through extortion, whereas coercion applies to a forced action. A confession to a crime may be inadmissable if coerced (forced).
