This posting is a coded message saying that Opsec is "Poor". (key is first capitalized word following ":" in 2nd line). The word obsec is intentionally misspelled as obsec as the "b" is pointing to the "P" in "Poor" for the first key word. This keyword is then to be used at the first comma in the message at "maintain obsec," = "Opsec = Poor". Another key may be the use of the word Maryland multiple times (re: I wonder who did it. <== no question mark, thus is a statement).
Follow up post was again a pointer to the word "Opsec"
