Jeffrey Dahmer admitted killing 15 young men. During his trial, the jurors considered his insanity plea. Wisconsin defines insanity using the Brawner rule, and the jurors decided that Dahmer was sane. What potentially caused the jurors to come to this conclusion?

The Brawner rule states that:

"A person is not responsible for criminal conduct if at the time of such conduct as a result of mental disease or defect he lacks substantial capacity to appreciate the wrongfulness of his conduct or to conform his conduct to the requirements of the law."

Anyone could clearly see that the Milwaukee Monster had the mental capacity to have killed and raped that many people ... According to an article published on "The New York Times", Dahmer "Had taught himself to live behind a mask of normalcy that hid his often contradictory emotions.".

So yes, Dahmer had emotional problems - - but not ones that left him mentally inept. Therefore, he was completely sane when he committed these grisly acts.

Dahmer was careful to kill his victims in a manner that minimized his chances of being caught suggesting that he recognize or appreciated that his behavior was bad/wrong and could control it

Explanation:The American Law Institute model stated that this kind of behaviour called insanity can be referred to as an individual is not accountable or responsible for criminal offence only if at the time the crime/offence was committed as a result of mental disease/defect he lacks considerable/essential capacity to recognize the essence of his crime or restrict his conduct to the rule of law. it is largely known to be one of the slightest victorious and accomplishing defenses of a criminal defense case and it is a very challenging work.
