Or retrieving your cane from the truck so you can walk....
All look like hostile aggression to trained LEO.
I think I saw the video of the events you are referring to and I could see why a cop could confuse a cane with a gun. That straight round shaft looked a lot like a barrel especially when pointed in the cop’s direction. Unfortunate event but I could see why it happened and if some of the people here are half so trigger happy as they claim they would have shot the guy too.
