State law allows the use of deadly force  or force intended or likely to cause death or serious injury  only if an unlawful entry is made or attempted in a "violent and tumultuous manner, surreptitiously, or by stealth" and a person reasonably believes the purpose is to assault someone or if a person believes the entry is made or attempted for the purpose of committing a felony. Under both scenarios, the person must "reasonably believe" the force is necessary to prevent the assault or the commission of the felony.
