I don't know what his intentions were, adding "lol" or "jk" afterwards doesn't make it go away. Honestly, I do think it was a joke from a dumb kid. I don't think he deserves jail time but I'm glad someone took it seriously enough to look into it.

No, it was not a smart thing to do. When you see things like that, you should think. Not regex for scary or even mildly offensive combinations of words, but think. Put that gray matter to some use.
Anyone who reads the comment he made, in its context, and thinks "whoa, better call the cops", demonstrates a serious failure to think.
