Final answer:
Specific intent crimes require a particular state of mind or intent. Key defenses may include lack of intent, mistake of fact, or intoxication.
Step-by-step explanation:
Crimes that involve specific criminal intent are known as specific intent crimes. These are offenses in which the defendant is required to have a particular state of mind or intent in order to be found guilty. Examples of specific intent crimes include first-degree murder, burglary, and larceny.
Key defenses for specific intent crimes may include lack of intent, mistake of fact, or intoxication. If the defendant can prove that they did not have the required intent for the crime, or that they made an honest mistake or were under the influence of drugs or alcohol at the time, it may be a valid defense.
It's important to note that the specific intent requirement and defenses may vary depending on the jurisdiction and specific laws of the country or state.
