their weapon. For example, if innocent bystanders are hurt or killed, there could be both civil and criminal liabilities even if the use of deadly force was completely justified. Some states technically allow an assailant who is shot by a gun owner to bring civil action. In some states, liability is present when a resident brandishes the weapon, threatens use, or exacerbates a volatile situation, or when the resident is carrying while intoxicated. It is important to note that simply pointing a firearm at any person constitutes felony assault with a deadly weapon unless circumstances validate a demonstration of force. A majority of states who allow concealed carry, however, forbid suits being brought in such cases, either by barring lawsuits for damages resulting from a criminal act on the part of the plaintiff, or by granting the gun owner immunity from such a civil suit if it is found that they were justified in shooting. Simultaneously, increased passage of "Castle Doctrine" laws allow persons who own firearms and/or carry them concealed to use them without first attempting to retreat. The "Castle Doctrine" typically applies to situations within the confines of one's own home. Nevertheless, many states have adopted escalation of force laws along with provisions for concealed carry. These include the necessity to first verbally warn a trespasser or lay hands on a trespasser before a shooting is justified (unless the trespasser is armed or assumed to be so). This escalation of force does not apply if the shooter reasonably believes a violent felony has been or is about to be committed on the property by the trespasser. Additionally some states have a duty to retreat provision which requires a permit holder, especially in public places, to vacate themself from a potentially dangerous situation before resorting to deadly force. The duty to retreat does not restrictively apply in a person's home or business though escalation of force may be required. In 1895 the Supreme Court ruled in Beard v. United States that if an individual does not provoke an assault and is residing in a place they have a right to be, then they may use considerable force against someone they reasonably believe may do them serious harm without being charged with murder or manslaughter should that person be killed. Further, in Texas and California homicide is justifiable solely in defense of property. In other states, lethal force is authorized
