They're worried that he has a little insurance policy that nobody knows about. That is all that is likely to keep the boy breathing. And I wouldn't be too surprised to learn that that's exactly what the laptop was.
Could be. Somewhere, he might have someone he can trust, and sent them an, “.. if I should mysteriously shoot myself twice in the back of the head....” file, which could expose crimes by Hillary that we have not even considered.
FWIW....saw some NYPD underlings talking online about the contents of the laptop. They were disgusted and even more disgusted with their overlords (upper mngmt) not allowing the contents to get out.
