Most people arent willing to discuss that on an internet board. Especially not with people they never met.
I will tell you what I know from the investigating officers standpoint.
Shots fired. First responders arrive. The shooter is put in some kind of custody.
Expect that: Custody. Weapon seized. Scared out of your mind that what follows is not your friend. A few are arrogant.
At some point, the investigating authority will either offer you a chance to get an attorney, let you go, telling you a grand jury will decide your fate, or lock you up.
There are good lawyers everywhere that can get you off if you are in the right. Some can get you off if you are guilty.
Sometimes it's a court appointed lawyer on taxpayer dime, the others, it's your pocket.
It's up to how the dice roll sometimes. There is no "one size fits all".
I've seen a habitual offender multiple felonious offender get a not guilty in a jury trial after killing one of his peers, and as the investigating officer, I was satisfied justice was served.
Lower Alabama, zero ccw carry insurance. Not even sure where to find it here.
Last family involved shooting cost 38k and took 7.5 years to resolve. Home owners insurance finally settled the civil suit.
Because one jurisdiction is so different from the next, most of the officers here, have a lawyer on call from the PBA, paid for out of pocket.
Like Snuby said, find something where you live and get it.
Ask your insurance agent. If it's a road rage shooting, they have gone after the car insurer.
Yard shooting, they have gone after the home owner insurer.
They will go after any insurer, because most will settle some nuisance fee to make it go away.
If this seems like a long post, pay attention, 7.5 years in the last family situation...
