I stand by the idea that it could be "stupid kids". There are kids, who don't pay attention in science class, who really don't know that such things are caustic and can cause chemical burns. It might be such a kid who did this thing. Or, I admit it could be a person who is hurting inside, who wants to hurt the world, even toddlers. We'll know more, when there is an arrest. I'm actually "on the fence" on what the nature(s) of the person(s) who committed the crimes are like, for now. All I ask, is that othere might consider the same.
ETA: My personal observations have been, that many kids who think random destruction and mayhem is cool, don't think science and schoolwork is cool. So, it follows that all they'd be thinking of is "chaos, break, smash" and not "I shouldn't do this, this could burn someone." because they are ignorant. I know there are others, adults and teens, who are smart enough to know exactly what it can do, and do the things out of malice too, though.
