They are mentally unbalanced. I doubt they even have a clue who their mayor is much less which politician is corrupt.
Maybe they think they are doing their part and are going to change the country by what they define as being a hero. Perhaps there was an event in their life (say a family member killed by an illegal) that pushed them off the deep end.
Most wind up dead so it’s difficult to get a profile on what motivates them to do what they do. What they all have in common as a motivator.
And, even if we knew there really is very little that can be done about it.
What ticks me off is that we know there are people like this out there that can appear any place, anytime. Yes, it can happen to you or to your loved one.
Gun control isn’t the answer so the answer has to be more people get involved in taking courses, training and carrying. Imagine had there been at least two or three people in that Walmart who could have shot the guy before he went on to take one more life.
Hell, imagine if someone was in the kitchen department and opened a package of knives and started throwing them at him.
People have to start being more proactive because the police aren’t going to be there in time and there are too many who are just oblivious.
And our laws need to change to make sure anyone who is trying to save people isn’t jailed or prosecuted for maiming or killing the killer.
