You also have to have the technical know-how and acumen to understand that your phone is a tracking device. Leave it at home. Your car also likely has a tracking device on it because car companies are selling that data. There are license plate cameras everywhere too, even if you drive a 90s beater. Also bullet ballistics is not a perfect science. You can also rebarrel your gun. You also want to have all this done years in advance so that when you decide you have a target, your purchases are hidden among a cloud of other things. If the gun isn’t yours, wipe it down and ditch it. Don’t leave fingerprints on the bullet casings. If they can’t place it in your hands at the time of the crime, then that leaves a reasonable doubt.
