Anyone with a firearm should realize that the day you have to shoot someone is probably the worst day of your life. Even with a justifiable shoot, most humans will be haunted by using potentially fatal force against another human, at least right-thinking ones should be. Once the threat has been neutralized, you better immediately call your attorney because you'll need that attorney (and possibly, more) in the months to come, even in a justifiable shoot.
This isn't like TV or Mexico where people get shot and law enforcement just looks the other way. The consequences of actions, whether intentional or not, can be huge. Hopefully, the presence of your gun defuses the situation and doesn't escalate it because that is the last thing that you want.
It could be worse, it could be the last day of your life.
Then, there’s the paperwork.
Exactly.
