There are a lot of Three and four letter agencies whose prime jobs are to focus on these issues!!! Guess what?!?! The answer to different Congressional committees!!! If you have a need to know then ask the appropriate committee members and they will give you the information you desire provided you have the need to know and the proper security clearances!!! So, Government is big enough and spends plenty of money as it is, let’s not make it bigger and more cumbersome!!!
