Harris did not resign!!

"sorry we were late but our chief of security resign and is working
in a fish and chips shop." then he had a rare thought, "hey you want
it? no one else wants to on the account of the yearly battle of the
paperclips."
Harris has not resigned from the post of security chief, he just took
a leave of abcense with no actually date of returning. He will
return to the BD in sometime (well, once its' to its' own realm is a
good starting date).
Lt. Charlie Edwards now commands the security department (or what's
left of it!) until the return of the Major.
