Explanation of the Many Investigative Organizations of the Department of Defense
Mike Angley, a retired UAF Colonel and career Special Agent with the Air Force Office of Special Investigation (the USAF version of NCIS of TV and Mark Harmon fame). He is the author of the Child Finder trilogy. http://www.mikeangley.com/
He gave a great presentation on all the various investigative organizations within the Department of Defense--what they do and what they don't do.
They respond to all felonies, murders, rape, etc. under their jurisidiction and do some counter intelligence.
Their are special operatives such as Navy Seals, Green Berets, and civilian special agents who can arrest both military and civilians.
They have concealed carry authority.
NCIS is all civilian.
None of them have a mortuary or crime lab. The Army runs the crime lab for all services.
(This means there is no Abbie or Duckie.)
They all do have forensic agents.
They all work together much better than they used to.
Of course there was a lot more--but if you want to know things like this, you should attend the Public Safety Writers Conference--all the experts attend.
