If that is the case, why does it mention having permission from an adult occupant of the household?
Also, if it intended to protect against prosecution for use of deadly force, why does the bill only state reasonable force is permitted to terminate unlawful entry when in other areas of the IC it specifies "to include deadly force"?
I'm not arguing, just asking. If what you say is the intent of the bill, why is that intent not specified, or even addressed in the text?
Permission - If you invite the police into your home, it is no longer an ILLEGAL entry, therefore, you may not resist them legally. If you do, you will be prosecuted. Furthermore, existing statutes determining exigent circumstances and probable cause still apply. If the officer has probably cause to enter your domicile, it is LEGAL and therefore, you may not LEGALLY resist them.
Reasonable force is determined by the circumstances, and the law does state to "terminate" the entry. The courts will fill in the blanks as cases are prosecuted. If someone is shooting at you, it is reasonable to shoot back.
Indiana law regarding the protection of your house has ALWAYS sided with the occupant over the invader when "use of force" is determined to be reasonable or not.
