According to American law, a defendant can only be convicted if he/she is guilty beyond reasonable doubt. However, the defendant should provide evidence that supports his/her defense. Here are some defenses that can be used in a criminal case.
It cannot be proved – Since the prosecution has to prove that the defendant is guilty beyond reasonable doubt, the defendants do not have to defend themselves if they choose not to.
I didn’t do it – If a defendant pleads that they did not do it, then they should provide evidence that shows inconsistencies in the evidence.
I have an alibi – If the defendant has an alibi, he or she can say that they were somewhere else when the crime was being committed.
I did it, but – The defendant can avoid punishment for a crime if they show that the defendant committed the crime to protect themselves or someone else from harm. In this case, the prosecution will look at who initiated the confrontation and if the force used was necessary.
The insanity defense – The idea here is that the punishment can only be given to someone who can control his or her action and understanding. However, this defense is difficult to prove, as the defense will have to prove the capacity of insanity.
It was the alcohol – If the defendant says that they were under the influence of alcohol or drugs, they could argue that they lacked the capacity to act clearly. However, this defense is weak, as intoxication is often not allowed as a defense at all.
