How can you say something like that?
maritiem
1. Have a thought.
2. Say the thought.
3. The thought may be expressed through either one's vocal cords, or through a text of some sort.
4. Sit back and watch people's reactions.
(It's a tad ironic that my previous thought would probably fall under that particular area.)
Oh, and I hope those who were hurt pull through all right.
There are a lot of crazy people out there.
Ultimately, it's just another sad example of extreme (and extremely stupid) human behavior.
