The policy issue for those who administer the criminal justice system is that, when planning their actions, people may be aware of many probable and possible consequences. So the decision to continue with the current plan means that all the foreseen consequences are to some extent
intentional, i.e. within and not against the scope of each person's intent. For example, A, a jealous wife, discovers that her husband is having a sexual affair with B. Wishing only to drive B away from the neighbourhood, she goes to B's house one night, pours petrol on and sets fire to the front door. B dies in the resulting fire. A is shocked and horrified. It did not occur to her that B might be physically in danger and there was no conscious plan in her mind to injure B when the fire began. But when A's behaviour is analysed, B's death must be intentional. If A had genuinely wished to avoid any possibility of injury to B, she would not have started the fire. Or, if verbally warning B to leave was not an option, she should have waited until B was seen to leave the house before starting the fire. As it was, she waited until night when it was more likely that B would be at home and there would be fewer people around to raise the alarm. Whereas intent would be less if A had set fire to the house during the day after ringing the doorbell to check no one was home and then immediately ringing the fire brigade to report the fire. On a purely subjective basis, A intended to render B's house uninhabitable, so a reasonably substantial fire was required. The
reasonable person would have foreseen a probability that people would be exposed to the risk of injury. Anyone in the house, neighbours, people passing by, and members of the
fire service would all be in danger. The court therefore assesses the degree of probability that B or any other person might be in the house at that time of the night. The more certain the reasonable person would have been, the more justifiable it is to
impute sufficient desire to convert what would otherwise only have been recklessness into intent to constitute the offence of murder. But if the degree of probability is lower, the court finds only recklessness proved. Some states once had a rule of
felony murder: a death that occurred during commission of a
felony automatically imputed sufficient
mens rea for murder. This rule has been mostly abolished, and direct evidence of the required mental components is now required. Thus, the courts of most states use a hybrid test of intent, combining both subjective and objective elements, for each offence changed. For
intention in English law, section 8 of the
Criminal Justice Act 1967 provides the frame in which the
mens rea is assessed. It states: Under s. 8(b) therefore, the jury is allowed a wide latitude in applying a hybrid test to impute intent or foresight (for the purposes of recklessness) on the basis of all the evidence. The
United States Supreme Court held in
Elonis v. United States that negligence is not sufficient to show intent, but did not rule on the question of recklessness. ==Offences of basic and of specific intent==
