While armed citizens must be trained how to act when police arrive, police trainers must also instruct line officers to know how to work with an armed citizen in ways that puts neither party in peril. Verbal communication training for officers is vital, of course, but fundamentals of cover and concealment must be repeatedly reinforced in pre-shift briefings and in-service training.
Further, officers must be reminded that an armed citizen who has just been in a high-stress, life-and-death situation may be suffering from the same tunnel vision and auditory exclusion police are trained to expect. These physiological effects may prevent an armed citizen from seeing a responding officer or hearing an officer's commands.
Nature Hates a Vacuum
Of course, the issue of an armed citizen potentially shooting a home invader is not limited to Santa Rosa County or even the entire state of Florida. It should be common knowledge that the common law principle of the "castle doctrine" allows individuals to use reasonable force—including deadly force—to protect themselves against an intruder in their home.
Further, according to the
National Council of State Legislatures
(NCSL), laws in at least 28 states specify that a person has no duty to retreat from an attacker in any place in which they are lawfully present. At least ten of those states include language stating one may "stand his or her ground."
