One item you excluded is that "physical force" does *not* included deadly force. Deadly force is defined in 503.010 (1), and is distinct and separate from 503.010 (4) which defines physical force.
Except there can't be deadly force executed on something that can't be killed. I bet the courts will ultimately rule that the drone is a person by proxy in this regard. These are monumental violations of private property and privacy. I don't know if Kentucky has recording consent laws, but in many states you cannot be recorded in a place of expected privacy without explicit permission from both parties.
Protection of property
(1) The use of physical force by a defendant upon another person is justifiable when the defendant believes that such force is immediately necessary to prevent: (a) The commission of criminal trespass, robbery, burglary, or other felony involving the use of force, or under those circumstances permitted pursuant to KRS 503.055, in a dwelling, building or upon real property in his possession or in the possession of another person for whose protection he acts
Justification and criminal and civil immunity for use of permitted force –Exceptions
(1) A person who uses force as permitted in KRS 503.050, 503.055, 503.070, and 503.080 is justified in using such force and is immune from criminal prosecution and civil action for the use of such force, unless the person against whom the force was used is a peace officer, as defined in KRS 446.010, who was acting in the performance of his or her official duties and the officer identified himself or herself in accordance with any applicable law, or the person using force knew or reasonably should have known that the person was a peace officer. As used in this subsection, the term "criminal prosecution" includes arresting, detaining in custody, and charging or prosecuting the defendant.
