After the reasonable attempt to flee the lead rider stopped and waited, no longer fleeing. The second bike followed the truck, not fleeing. Attempted to run over his bike. Deadly force cannot be used to protect property. In order to legally use deadly force you have to ne able to prove you didn't provoke or escalate the situation in any way. Running upto and opening the guys door. Stopping and standing in front of his truck preventing him from leaving. Looks like provoking / escalating to me.
