What level of assault is John Smith guilty of when he assaults a person with a dangerous weapon and inflicts substantial bodily harm?

John Smith is guilty of second-degree assault because this level of assault specifically involves the use of a dangerous weapon and the infliction of substantial bodily harm. In Minnesota, second-degree assault is characterized by an intention to cause bodily harm to another, coupled with the use of a weapon that could potentially cause significant injury or harm. The term "substantial bodily harm" refers to injuries that cause temporary but serious disfigurement or temporary loss or impairment of a bodily member or organ, which aligns with the details of the incident described.

First-degree assault typically involves causing great bodily harm or the use of a firearm during the commission of assault, which is not indicated in John's actions. Third-degree assault is generally associated with a person who causes substantial bodily harm but does not involve the use of a dangerous weapon. Fourth-degree assault is the least severe and often applies to situations involving minor physical harm or threats without a weapon. Thus, the elements of the case clearly align with the criteria for second-degree assault, making it the appropriate designation.
