§ 9.41. PROTECTION OF ONE'S OWN PROPERTY.
(a) A person in lawful possession of land or tangible, movable property is
justified in using force against another when and to the degree the
actor reasonably believes the force is immediately necessary to
prevent or terminate the other's trespass on the land or unlawful
interference with the property.
(b) A person unlawfully dispossessed of land or tangible,
movable property by another is justified in using force against the
other when and to the degree the actor reasonably believes the force
is immediately necessary to reenter the land or recover the
property if the actor uses the force immediately or in fresh pursuit
after the dispossession and:
(1) the actor reasonably believes the other had no
claim of right when he dispossessed the actor; or
(2) the other accomplished the dispossession by using
force, threat, or fraud against the actor.
§ 9.44. USE OF DEVICE TO PROTECT PROPERTY. The
justification afforded by Sections 9.41 and 9.43 applies to the use
of a device to protect land or tangible, movable property if:
(1) the device is not designed to cause, or known by
the actor to create a substantial risk of causing, death or serious
bodily injury; and
(2) use of the device is reasonable under all the
circumstances as the actor reasonably believes them to be when he
installs the device.
