Rule numero uno. NEVER EVER LIE TO AN LEO. EVER Do it once nothing you say will be believed after that.
I know of some one that was involved in a deadly force situation involving a family member's exhusband. There were a lot of things against the exhusband. Deadly force was used and BG was pronounced dead on the scene. He was asked by the LEO on scene if he had any other weapons. He awnsered truthfuly that there was a single shot shotgun in the trunk of his car. LEO left it there.
The man went before a grand jury that took 30 minutes to come back with a justifiable use of deadly force decision. His gun was returned to him the following day.
Note I worked with him for a while until he retired. He is one of the nicest people you could ever hope to meet, and a very humble person.
No matter how many times you do it and nothing happens it only takes something going wrong one time to kill you.
