Shjustme
Adultery doesn't transgress the law of the land, and in case you hadn't noticed, the Forces don't make a song and dance about it like they once did [rightly excepting across rank/command chain boundaries].
The RAF are not going to hang cpl smith because he decided to commit adultery with someone outside.
Would it have made a difference if it was his [unmarried] partner that he cheated on? Or does it only matter when there is a sheet of paper called a marriage certificate involved? Or the rank of the individual - where do you start to get uptight - sac, sgt, sqn ldr, air marshall? Anyone?
Time to climb out of the dark ages and join the real world. Sh*t-canning someone from his professional job for a domestic sin does not make sense in any way, shape or form - that's when you end up cutting off your nose to spite your professional face.
The media delight in kicking anyone who would help sell a few extra copies - do you think they would care if it was cpl Smith and Mrs Jones?
