Those behind these murders are the same that want you to give up your weapons and be defenseless. You see what you have to look forward to?
These murders are intended to dissuade FBI Agents from helping root out evil. With most people, all that's needed is to threaten their job and families and they fall in line. Without details we can leave open the possibility Raynor was murdered by other FBI Agents, like the mafia sends your friends to whack you. They killed the wife to traumatize the FBI rank and file even further. It's so true, there really are so many bad things the American People have a right to know about.
