What is Virginia's Code Section on Use of Deadly Force?
It depends on the state. A very basic rundown is: in some states, a homeowner can use deadly force once an intruder has entered the dwelling. In some states, a homeowner can use deadly force before the intruder is in the house as long as they suppose a threat and are on the property. In some states, the homeowner cannot use deadly force unless the intruder has a weapon.
Nondeadly force can be used to repel either a nondeadly attack or a deadly attack. Deadly Force may be used to fend off an attacker who is using deadly force but may not be used to repel an attacker who is not using deadly force.
what dicates the reason a security officer can escalate the use of force
It depends on what you mean by "threatened." Note, the following explanation is very general, and in no way should be considered legal advice or advice on when to use a gun. The use of a gun on another person is considered deadly force, and the implied use of it (by showing it, for instance) can be considered a threat of deadly force. As a generality, you can only use or threaten to use deadly force against someone who is trying to use deadly force against you. If someone has threatened, for example, to punch you in the mouth, and you use, try to use, or threaten to use deadly force, you have, under most circumstances, advanced higher within the force continuum than the other person. Most of the time, that will get you into trouble.
a landmark decision called Tennessee v. Garner in 1985. The court ruled that the use of deadly force by law enforcement is only justified when there is an immediate threat to the officer's life or the lives of others. This decision established the "objective reasonableness" standard for evaluating the use of deadly force.
The Departments Policy on the use of deadly force limits an officer .
It depends on where you are, but in the United States, generally speaking, you can use deadly force to protect yourself and/or an innocent third party. So, in any situation where deadly force is justified, you can protect anyone that needs to be protected. Law varies slightly from state to state, so there may be subtle differences depending on your location, so you should check your local laws.
Yes, only to protect though. Unlike Area 51, military bases are only untitled to use deadly force if absolutely necessary
Use of Deadly Force in DefenseThough I'm sure the majority of people would not take any pleasure in killing another human being to defend themselves or their property, I definitely believe that using deadly force should be a choice they can make without repercussion. ---Can the government use deadly force to protect their personal and government property?
