Wait no longer.
I do have to give you credit on that, and frankly I knew it was coming because after I wrote that I googled it myself and got the same case here that you did.
Nevertheless, I'm going to stand by my original point even if it isn't flawless. Your original inference was that it is a common, regular occurrence for high school shooters to make bail and be released. I will continue to maintain that it is not, even in view of a singular example to the contrary. I might even be tempted to question whether or not it is more common for the shooter to commit suicide than it is for them to be released, but that becomes a whole other discussion.
Let's just be clear in giving credit where it's due: I acknowledge that you succeeded in producing an example.
But I continue to reject the premise that it is a regular occurrence. The surprising thing about the example you produced is that it occurred in Texas. It has to some measure shaken my faith in the US justice system which I can only admire from afar, living as I do in a country where killers really do face minimal prison time, if any at all. Unfortunately, I could produce links all day long to show you the failures of the Canadian justice system.
