You are not shooting at them, you are shooting at their vehicle to disable it, they have 6 (7) options,
1. Get out and run away
2. Get out run away to find cover then shoot back when said shooter least expects it.
3. Hands up
4. Hands up and try to roleplay situation
5. Shoot back (engages you to him and risk dying) this is the sketch part, Say he does shoot, if robbers hold fire until Engagement text is sent. can we then shoot him?
6. If you have time, jump out and repair the vehicle
7. Jump out and repair the vehicle or call the cops
even if he runs away or shoots back you still can't kill him. If the said player chooses to hide behind his truck or go for cover to slowly pick robbers off he can use that to his advantage, since we still can't kill him until text has been sent
