The extortion, in law, is a crime committed by those who, by force or threat, forcing one or more persons to do or not to do some act in order to gain an unjust profit.

A racket is a service that is fraudulently offered to solve a problem, such as for a problem that does not actually exist, that will not be put into effect, or that would not otherwise exist if the racket did not exist. Conducting a racket is racketeering.Particularly, the potential problem may be caused by the same party that offers to solve it, although that fact may be concealed, with the specific intent to engender continual patronage for this party. An archetype is the protection racket, wherein a person or group indicates that they could protect a store from potential damage, damage that the same person or group would otherwise inflict, while the correlation of threat and protection may be more or less deniably veiled, distinguishing it from the more direct act of extortion.

Dwailin where are you from?

Make a practical example?

If I control the waste racket I do racketeering, if you have a company and I tell you that you must give me $ 10,000, for example, if you want operate in the waste business or I'll burn trucks of your company, then commit the crime of extortion.

I hope to be clear and useful.
