First, we have to define a non-legal term here. What is a crime? If we go with the normal definition, a crime is a violation of the laws of the state. If you define this word differently, you may come up with a different answer than I did.
Given the situation as described, you have committed a crime. You have committed the offense of Murder in violation of Penal Code section 19.02. Please note that this chapter reads as follows:
It is clear to me that you have intentionally killed a human being, thus have committed a crime as shown above. Now, were you able to do so legally? Yes. There is a justification of self-defense and we all agrree it applies. But what most of you have forgotten is that justification is a defense to prosecution, not an exception from the law. Penal Code chapter 9.02 shows us this as follows:(a) In this section:
(1) "Adequate cause" means cause that would commonly produce a degree of anger, rage, resentment, or terror in a person of ordinary temper, sufficient to render the mind incapable of cool reflection.
(2) "Sudden passion" means passion directly caused by and arising out of provocation by the individual killed or another acting with the person killed which passion arises at the time of the offense and is not solely the result of former provocation.
(b) A person commits an offense if he:
(1) intentionally or knowingly causes the death of an individual;
(2) intends to cause serious bodily injury and commits an act clearly dangerous to human life that causes the death of an individual; or
(3) commits or attempts to commit a felony, other than manslaughter, and in the course of and in furtherance of the commission or attempt, or in immediate flight from the commission or attempt, he commits or attempts to commit an act clearly dangerous to human life that causes the death of an individual.
(c) Except as provided by Subsection (d), an offense under this section is a felony of the first degree.
(d) At the punishment stage of a trial, the defendant may raise the issue as to whether he caused the death under the immediate influence of sudden passion arising from an adequate cause. If the defendant proves the issue in the affirmative by a preponderance of the evidence, the offense is a felony of the second degree.
So, you have committed a crime and can be arrested and charged for it. You should be found not guilty by virtue of the justification defense, but you did commit the crime.It is a defense to prosecution that the conduct in question is justified under this chapter.
And when you think about it, we all know that this is true since we can all think of examples of people who justifiably used force and were still charged and tried. We even talk about having a lawyer available to defend us if we get involved in a shooting. If it was not a crime, could a lawyer defend us from the police?
