(2) Danger to Other Persons. If a person is justified or excused in using force against another, but he recklessly or negligently injures or creates a risk of injury to other persons, the justifications afforded by this Chapter are unavailable in a prosecution for such recklessness or negligence, as the case may be.
(3) Civil Remedy Unimpaired. That conduct may be justified or excused within the meaning of this Chapter does not abolish or impair any remedy for such conduct which is available in any civil action.
(4) State Prosecution of Federal Public Servant. The defenses of justification and excuse may be asserted in a state or local prosecution of a federal public servant, or a person acting at his direction, based on acts performed in the course of the public servant's official duties.
