I agree with criminal liability in the event an innocent bystander is shot by a legit shoot.
I question this being a legit shoot.
Facts are few and far between so far and I haven't been able to dig up anything that seems trustworthy.
Witnesses and police outright dispute that the car carrying the aggressors fired any shots, which is what the good citizen is claiming. That they shot and that they shot first in a drive-by style shooting shortly after his party arrived home.
Then you have his actions leading up to the events that I highly doubt anyone on this website would advocate. And his handling of the subsequent shooting, which I know would not be advocated by anyone on this website.
His character is in question, not whether a criminal should be held liable for harm to bystanders and property.
