The vandalism is about the only thing the DA could prosecute.
This is the second time you have called this Vandalism, IT IS NOT !!
It's Criminal Damage to Property and over $1200 is a Felony
(vandalism is defacing a Park or a wall on a building)

He premeditated the plan of grabbing a firearm and shooting down your 6K drone.
He's laughing now.
