Lots of different variables in play in a situation like this that go even beyond the difficulty of the “standard” defense of a third party questions. I’ll also say up front that I’m not a lawyer and I don’t have all the answers, but some things to think about...
Were the protestors part of a legal, permitted rally? Or were they illegally blocking the street? Not saying either necessarily justifies a car hitting them, but there is a significant difference between a car that knowingly accessed a closed street or drives into a park to hit people versus a guy who was driving home from dinner with his family who gets trapped by a mob of people roaming the interstate.
What were the actions of the protestors at the time? Were they standing in a line saying “none shall pass” but were otherwise maintaining distance from the vehicles? Or were they walking amongst the vehicles? Were they attacking vehicles? Were the protestors pointing guns at vehicles? Did they have Molotov Cocktails and threaten to burn the vehicles and those inside?
The point is, there’s a LOT of stuff that could have happened that you, either in relation to defending yourself or as a defender of a third party, may not know. And it directly affects the driver’s justification for use of force, and may also affect your justification of use of force.
On defending a third party, if someone decides to intervene between two parties with lethal force, you really need to have a good understanding of the entirety of the situation and choose the right side to intervene against. And remember that just because someone is wining the fight at the moment doesn’t mean that they weren’t the victim who was attacked first.
Now, looking more to the practical side:
While the incident prompting the driver to accelerate and drive through the crowd could have happened a few blocks away (and possibly out of sight of the person defending themselves or a third party), there have been several videos over the last few months showing what happens when a driver goes through a “protest”, stops, and then the “protestors” catch up with them. In the few that I’ve seen, the driver usually ends up in the hospital with severe injuries. Once a driver reaches the threshold of “I’m being attacked and the only way to save myself is to drive through a group of people”, don’t expect them to stop until they’re well away from the WHOLE crowd.
Another couple of things to ponder. A few months ago, I believe there was an incident on an interstate where a Jeep was driving through a protest (maybe after being attacked, maybe not, I can’t recall). Someone in the crowd decided to take a few shots at the Jeep as it was passing. He missed the Jeep and hit other demonstrators down range. I think that’s an outcome we’d all like to avoid.
Second, if by shooting the car your goal is to stop the vehicle, make sure you have a plan for what happens AFTER the vehicle stops. If it’s one guy and you hit him, he may be incapacitated or he may be wounded but active. He’s not gonna be happy and you have fixed him in position and taken away his best (and maybe only) option of escape. If he’s armed, his last option is shooting his way out. You just forced him into that situation AND became the highest priority target on his list.
Another thing to worry about - and I’ll admit this is a bit extreme, but the way things are going, it’s worthy of thought. We’ve seen pics and vids of guys in body armor with rifles (I hesitate to call them “militias”) but what if those guys are actually squared away and understand team tactics? You just disabled their vehicle. The standard reaction to “CONTACT, VEHICLE DISABLED” involves LOTS of rifle fire, all headed your way.
So I guess in summary, this is a very difficult and complicated topic, that just gets more complicated as the variables increase. The best option is not to get involved, but if you do decide to fire...
- Know the entire situation and whether or not the use of force is justified
- If you do decide to fire, know who/what is down range of your target
- If you succeed in disabling the driver or vehicle, be prepared for round 2
