While I agree you are correct on most of what you stated. There are a few things that you are not correct about IMO.
One must be 18 to aquire a licence to carry a handgun. There are exceptions in IN code for a person under 18 to carry. Such as on real property possessed by their parent or guardian, while hunting, or engaging in or traveling to an from an organized competetion or practice for such and target shooting in a approved area and under adult supervison. But they cannot just carry around town for self defense unfortunatly."One must be 18 to carry a Firearm."
While most LEOs believe you must show your license if you are carrying, there is nothing in IN code or IN case law(that I can find, if you have something I would love to see it) for you to do so. Although IN code states that it is illegal to carry without having in your possesion a LTCH. You are required to provide a Drivers license, or name, date of birth, and address, if the officer in good faith believes you have commited an infraction or ordinance violation. Just because you are carrying does not give them a good faith belief that you have commited an infraction. Just like they are not allowed to stop someone for driving to check to see if they are licensed without witnessing another unlawful act. But that has not been decided by case law.While in Indiana, if any Man goes armed in Public with a Handgun, then, a Officer may, with the foregoing procedure, ask of Him to make good His name, His address, and His birth date, while that Man is armed in Public or any Public Place. Also, you must show your Handgun Carry License as well.
Federal law prohibits carrying within 1000 ft of school property unless licensed by the state(or other exemptions such as living within that distance) which a LTCH covers. Indiana does allow possession of firearms on school property with serious restricions, you must be authorized by the school to do so, or if you are operating a motor vehicle and dropping off or picking someone up from the school(you are not allowed to leave the vehicle ) Indiana does not differentiate between firearms for the purpose of those statues, it doesn't matter if you possess a single shot firearm or a full auto.However, Indiana regulates further that Firearms may not be carried into any School or into any Airport, passed the controlled access points... both of these restrictions is per Federal Law. The severity of the offense depends on what type of Weapon is involved, and if a Person is actually on the Aircraft or inside the School. Indiana never really says if having a Permit is a defense to either Crime, or if the School prohibitions apply to Colleges and Universities, and other Adult Education Centers. Indiana tried to clarify the Law, but failed, when SB0012 was drafted to allow Firearms into Colleges and Universities and place them under State Preemption.
That section of code refers to the disposal of confisated firearms, the code for the actual confiscation of them falls under other IN code. Which is the same for any unlawfully possessed item. ie a stolen object or anything else that the person is not allowed to possess by law. I'm too lazy/not bored enough to search through the code for the relevant section/s.In Indiana, authorities may confiscate a unlawful Pistol, per 35-47-3-1.
All standard disclaimers apply IANAL, TINLA, YMMV etc.
