I'd be interested to hear the outcome on this one. I'm guessing that the driver could be accused of assault with a vehicle, making the other customers fear for their own safety. I think there will be an argument that shooting his tires out wasn't justified...how ever appropriate we might think it was for the situation.
Justified, more than likely no. I'll be surprised if the county prosecutor doesn't come after them. That being said the area has a lot of tweekers. The store that was stolen from was once a grocery store that failed in 2008 and the tweekers took over. The property owner and sheriff kicked them out and was able to sell the building.
Guessing people were fed up and tired of that in the community.
