Personally I think something has gone on. Year on year budget cuts, relatively low moral, declining esteem of and within the military, increasing demands for Trident to be relocated or scrapped all together....over familiarity among defence workers with security services and their procedures? Maybe it really leaps out at you when you see it for the first time?
That's still not an excuse to leave these very dangerous weapon platforms and systems in the position where they are likely to take out 50% of the population.
It's in the public interest to investigate the allegations made fully, and I hope that's exactly what the MOD is doing. Criminal prosecutions against the whistle-blower should be the last thing in mind when the safety of 60 million people is reported to be at risk.
