There’s a wide range of possible defenses that can be used in violent crime cases, but the defense depends on…
The type of charge,
Whether it resulted in death,
Whether there was an element of self-defense,
If there is uncertain evidence,
The amount of force, threat, or intimidation used in a robbery or carjacking, or
The amount of force or violence used in a rape.
The only way to really determine what defense might be right for your specific case is to consult with and hire an experienced attorney who can evaluate the facts of the case. An experienced attorney will be well-versed in the laws and statutes at play and will be able to piece together a defense based on the law and the facts present.
