Ummmm bad use of a title.. "BTK" is a serial killer here in the States. He's serving multiple live sentences in prison for things that can't even be described in a public forum. Colorful photo name, but one steeped in the blood of innocents.
Sir, I'm not going to sway from my opinion. Others can use the words. Horrible people and horrible things are part of this life everyday. There's no escaping it, so why linger? If tragedy strikes, such as murder or suicide, we must assist all those hurt and then move on. His name is not the horror. What he did is the true horror.
I'm studying psychology and I recently wrote a paper about this serial killer - so yes, I do know him. But as nocoisreal said: the name is not reserved for anyone. And actually I used it in this case because of a songtitle.
