No, it's not a process it's a methodology the
-ology part being the key. It could be applied by the most expert of practitioners and still be ineffective.
Somebody mentioned psychology. That's only part of it; you are dealing with physiology and anthropolgy and a couple of more arcane disciplines as well. BD&E can be useful and give results in a controlled environment, it can not pick a "bad guy" out of a line of passengers from across the lobby which AIUI is the BDO's
modus operandi.

Maybe, maybe not. If you really are fascinated, put aside your bias and study the subject. The internet is just a start but more definitive (and less hysterical) information is in the local Public or, even better, University library.
If any methodology is used incorrectly, it gives incorrect results. Mostly; even spotniks can get lucky.
