Putting to the side all of the legal elements of owning and carrying guns in the US and self defence etc.
From both a morality and sanity viewpoint, it is not OK for any citizen, nevermind a 17 year old kid, to intentionally confront people they don't agree with, while armed with an assault rifle. Travelling to another place specifically to do that makes it even worse.
Two people have died and another is severely injured.
The 17 year old has also ruined his own life, regardless of what the courts decide.
Everything about the situation is wrong.
