Why would anyone do that? That is completely fucked up!
Yes it is.
Good to know some "loving Christians" from the latter day saints are on the side of people who make "crush" videos!
It could just as easily been some sick fuck teenagers, like the guy who lit that bag of cats on fire that one time. We don't know who did it, and unfortunately it looks like the police can't be arsed to investigate it.
What a sick bastard. I didn't watch the video, I don't think I can, I hope this sicko gets the book thrown at him.
They have no idea who did it. Even the FLDS is just the best guess of the guy who found the cat, due to his prior history with them.
ADDED LATER:
Who are these people? Saturday morning cartoon villains?
Someone get 4chan please.
As satisfying as 4chan's retribution can sometimes be, in this case it would almost definitely be misdirected. Without any web presence to trace, save for that of the guy who rescued the cat, they'd likely just lash out at the FLDS. The wrath of 4chan is not something I personally would wish upon anyone based on naked speculation.
