Sorry mate - I think you're b*ggered. The best spin you can put on your SF membership is that you were extremely immature at the time - work backwards from that and it only gets worse. Think of it from HMGs POV - should they take the risk in trusting you with classified info and ops - probably not if you're honest with yourself. Don't think you'll have that much joy south of the border either. Vetting for Gardai SB and IDF related work is very strict and shinners are just as much the enemy there too. If it's any comfort, being "cleared" is no big deal - theres more to life than having to sit in front of some old ex-copper vetting officer having to confess your drinking habits and sexual preferences - you can do that from the comfort of your own room on AARSE!!
