Strict liability crimes are crimes in which the prerequisite mens rea is absent. Mens rea has to do with the formulation of criminal intent before the crime is committed. Good examples of strict liability crimes are: parking your car in a no parking zone. In other words, you did not realize the zone was a no parking zone. Selling alcohol to an underage person/ alcohol was sold to this individual but the seller did not know the person was under age. This particular strict liability crime has come under fire in recent years. Another example is: engaging in sexual intercourse with an under-aged person when the other party is of age. This law, of course, is meant as a protective mechanism to our youth.
