You have now attempted to compare a crime requiring intent with a crime that does not require intent, which is not going to help your argument. As JakeB posted, the crime of theft requires that intent be 'knowingly' and this is an element of the crime that must be proven. Speeding tickets, parking violations, sale of alcohol to a minor, and statutory rape are all examples of strict liability crimes.One of the simplest situations would be a speeding ticket. Can you prove a person intended to speed? Doubtful unless the speed is extreme. A limited speeding violation can simply be blown off as "I didn't intend to speed. I just was not aware of < how fast I was going; the speed limit on the road; and other such stories> Has that swayed the prosecution of a speeding ticket? And if you want to argue that a speeding ticket is not a criminal charge,
strict-liability crime: A crime that does not require a mens rea element, such as traffic offenses and illegal sales of intoxicating liquor. (
Black's Law Dictionary (8th ed. 2004))
This is just a segment of one of Arizona's speeding statutes:
A.R.S. § 28-701.02
A. A person shall not:
1. Exceed thirty-five miles per hour approaching a school crossing.
2. Exceed the posted speed limit in a business or residential district by more than twenty miles per hour, or if no speed limit is posted, exceed forty-five miles per hour.
As you can see there is no mens rea requirement in that statute so the state needs only to prove that you committed the Actus reus and once that is established beyond a reasonable doubt you are guilty. JakeB's posts do a good job at explaining the need to prove the concurrence of the elements when prosecuting a crime.
