For those thinking you will not get the gun back you are very, very wrong. In fact most cases you would get it back withing 24 hours of a grand jury deeming justifiable use of force. They have to by law regardless of the state.
I personaly know someone that shot and killed an armed intruder. The day after he was cleared by the grand jury he drove to the county sherriff's office, and withing 30 minutes he was driving away with his gun. He did not get the remaining 5 rounds of ammo that were in it the night it was turned over to the LEO's.
No matter how many times you do it and nothing happens it only takes something going wrong one time to kill you.
