What is One of the main semantic problems with using sleepwalking as a defense for murder is?

One of the main semantic problems with using sleepwalking as a defense for murder is the potential for malingering.

Malingering refers to the intentional production of false or exaggerated physical or psychological symptoms in order to gain some external benefit, such as avoiding punishment or obtaining compensation. In the case of sleepwalking, a defendant may claim to have been sleepwalking at the time of the murder in order to escape criminal responsibility. However, it can be difficult to determine whether a defendant is truly sleepwalking or whether they are malingering. This is because sleepwalking is not a well-defined condition and there is no clear consensus on what constitutes sleepwalking. As a result, it can be difficult for a jury to determine whether a defendant is genuinely sleepwalking or whether they are simply pretending to be sleepwalking in order to avoid punishment.

Another semantic problem with using sleepwalking as a defense for murder is the fact that sleepwalking is not always considered to be a complete defense. In some jurisdictions, sleepwalking may be considered to be a mitigating factor that can reduce a defendant's sentence, but it is not always considered to be a complete defense. This is because sleepwalking is not considered to be a complete excuse for criminal behavior. A person who is sleepwalking may still be held responsible for their actions if they were aware that they were sleepwalking and they could have prevented their actions.
