As Predators and their "Apologists" (aka co-conspirators) have everything to lose by the truth about who they are and what they are all about getting out to the general public, they will do whatever they deem to be necessary to ensure they silence anyone who would start disclosing about them.  They are able to manipulate, deflect, and talk circles around most people. However, when they encounter someone who they know is on to them, who understands their predatory nature, they will go into a very predictable attack mode, to ensure they silence the threat.
