No, not at all! The threats were in "relation to his employment with JMM".
Even if the brown envelope arrived

.. and this is ONLY a scenario .. CC could have denied the allegation but can't any longer .... thus violation of a policy and termination.
I don't know!

I'm still stuck on "threats in relationship to his employment with JMM" and I believe the threats were valid and real.
I'll even venture that the killer had such rage and hatred towards Coleman as to not only kill his wife and children but to plan the act methodically and purposefully so as to implicate Coleman.
I just don't buy Coleman painting messages on his own walls.
