You don't trust a random unarmed stranger. Why would you EVER trust a group of well-motivated, trained, armed, and protected professional killers?
The only thing more mind blowing than the scam itself is that we all sit around and don't seem to care as these people eat our young alive. In fact, they worship these institutions. It's their "alma mater," after all, it's like family, isn't it? Some even DONATE to them!
