What can cause empty-hand techniques to escalate to deadly force?

Empty-hand techniques can escalate to deadly force primarily due to their potential to inflict serious bodily harm or even death. When a defensive tactic is employed, it may initially be intended as a non-lethal means of control or restraint. However, certain techniques, if applied incorrectly or with excessive force, can result in severe injuries, such as broken bones, internal injuries, or strangulation. Moreover, the situation may evolve rapidly; if the defender perceives an immediate threat to their life or the life of others, they may feel justified in escalating their response to a level that includes the use of deadly force as a necessary means of protection. This potential for grave consequences in a heated confrontation highlights the importance of understanding the risks associated with different levels of force and using appropriate techniques based on the circumstances.
