In practice it only applys to civil actions.Thanks for the info, mobeydick.
So this sounds like if, after an investigation, IF the investigation finds the force to be justifiable then that's when the immunity comes in. Do people get arrested while the investigation goes on and then charges are dropped if it's found to be justifiable? Someone has to rule it as justifiable in order for the civil action immunity to kick in. The person isn't immune to "criminal prosecution" until their actions are deemed justified...clearly, Mr. Dunn's actions weren't immediately deemed justified, and still haven't been. Personally, I would hope someone using force would be detained during an investigation--who is to say they aren't a danger to themselves or others until a thorough investigation is completed.
So, I'm not really sure how the immunity thing applies here?
If LE doesn't charge someone, Civil action cannot be taken. LE made the decision. If LF sends it to the DA and he does not indict the DA made the decision, no civil action can be taken. If the DA sends it to and GJ and they don't indict the GJ made the decision no civil action can be taken. If someone is charged by any of those options and the person claims Selfdefense a Hearing to proceed is ordered, at that time a Judge will hear the states case and the defendants counterclaims and the judge will rule to either proceed or to order the state to dismiss the charges. If he judge orders the case to proceed and the defendent is found not guilty no civil action can take place. If the Judge rules the state doen't have enough evidence to presume a reasonable conviction the will order a dismissal, at that time no civil action can take place.
This whole law was enacted to prevent relitives of people killed in the commision of a cirme from suing the people who killed them!
