Legality of commiting a crime, car theft
<p>I am interested in knowing about the legality of committing a crime in a situation that disable another crime from happening while protecting one's life or property.</p>
<p>For example: A man a has a car. There is an evidence of a different man's intention, man B, to steal a car to the man A. The man B has to use his car to get to the place of residence of man A. Can man A legally steal man's B car to disable the intended car theft from happening?</p>
<p>Thank you.</p>

<p>&quot;Necessity&quot; is a defense against criminal prosecution in many jurisdictions. However, what counts as &quot;necessary&quot; is situation dependent. The essence of an action being &quot;necessary&quot; is an action is necessary if there is no other means of preventing a crime. In your scenario, there are many non-criminal alternative means of preventing the theft, such as calling the police, moving your car, or locking it, so stealing a person's car is not necessary. The conclusion that a crime &quot;will be committed, but for...&quot; also has to be clearly supported by reason.</p>
