When should a taser not be used regarding a subject's possible injuries?

The use of a taser should be avoided when a subject has known pre-existing injury areas because delivering an electrical shock can exacerbate existing injuries, potentially causing harm or worsening the condition of the individual. This consideration is crucial for ensuring the safety and well-being of the subject. Recognizing the signs of prior injuries allows law enforcement officers to act responsibly and with caution, adhering to the principles of duty of care and minimizing unnecessary risk during encounters that involve the use of force. Hence, the presence of such injuries necessitates an alternative approach to managing the situation, rather than deploying a taser which could lead to serious consequences for the individual involved.
