This is a good case that highlights a lot of what I was saying in this thread
http://www.thehighroad.org/showthread.php?t=593501
Just as in that thread the true answer of whether it is legally justified is "depends" and in this case the guy was even being attacked by three people in an ongoing attack. Far from just a single blow or threatening situation with multiple potential attackers.
There is a lot of discretion, and a jury gets to decide what a "reasonable person" would do and hence if the response was reasonable and justified, and the evidence a jury is presented with may be heavily biased against you. And just as I cited in that thread the versions of events cited by the attackers and who they were with will likely be very different and benefit them. As well as other possible witnesses, like someone that first turns and looks when they see and hear shots fired but don't understand what led up to that and so become biased against the defender.
Yet the jury and others may believe multiple portions of different stories, or think the truth is someplace in between, even when some versions are complete lies.
You can be entirely legal and go to prison, and many people do.
The other thing worth noting is the cost and resources required. Someone without those resources or a more typical public defender would have likely gone to prison.
From the bail money, to the defense money, to the need to use another home because he was prevented from being within a 5 mile radius of his own home, etc
A family man with a house, such a committed mother, and a community willing to donate significant funds is in a much better position to raise finances and create a legal defense than many other people.
He had someone let him stay with them, and got out of jail. Having to pay for a new residence while still paying the mortgage on his home that he can't go back to would have added extra difficulties to deal with at the same time. Then he had his someone to get his clothes and other things from his home as needed while he lived elsewhere.
A lot of other people made things much easier for him.
He had a whole team of some of the best expert witnesses working for free, another unlikely scenario for most people.
Someone that had remain in jail would have had great limits on their ability to even do research or rally people, even a competent attorney in jail would find it hard to put together a defense with limited resources, no access to technology, and slow tedious access to outside attorneys and maybe rare use of some law books.
Someone competent at forming a legal defense in the real world and good at doing research would be quite limited in an empty jail cell most of the day. While the days count down, time runs out to do investigations in time, and the trial gets closer.
Another thing to take away is that the jury makes all the difference in a discretionary situation. The law only partially matters. The makeup of the general population in an area greatly effects the odds of the typical jury.
Even in places with better laws you can sometimes have worse juries and vice-versa. Some regions of the country have jury members far more likely to convict you. For example California has some really good defense laws and has for longer than castle doctrine has existed in most of the nation, better than many other parts of the country with better gun laws, but your typical jury in California is going to be a whole lot worse than many other places.
While you might fare better in a place with worse laws but better juries.
Even in Arizona it took him two criminal trials to prevail, and he never actually was found not guilty, just got hung juries, with some of the best self defense expert witnesses possible, and he still settled the civil suit and his attackers got $100,000.
His attackers also put out a restraining order that prevented him from owning firearms after the two criminal trials and civil settlement, and even stated the primary reason for the restraining order was simply to prevent firearm ownership!
during the hearing, the plaintiff told the magistrate
that she really didn’t have any problems with Hickey, and that he was welcome
to come over to her house to have a soda if he liked so long as he
didn’t bring a gun along. She stated that she wanted the injunction to prevent
Hickey from possessing firearms.
