As someone who has actually worked for US intelligence in the past, and still holds a clearance after doing time for J6, I can assure you it's not just crap.

That'd actually be pretty awesome...if true, and as much as I'd like to believe what you've asserted here, unfortunately, as I'm sure you can understand, these words alone really only amount to being a common appeal to authority fallacy...at best.
Anyone online could claim to have worked for "US intelligence", and "still holds a clearance" despite, as implied, (a) no longer working for such, and also (b) doing time.
For all you or anyone else knows, I might've previously worked for/or currently work for an intelligence agency. Yet whether true or not, I could just as easily, as you have, publicly assert the affirmative with nothing but an appeal to authority too.
Regardless, security clearance, even at the basic civilian level, doesn't simply persistent indefinitely. Why? Because this would be a glaringly significant security risk wouldn't it.
What you Euros don't understand is that we're pretty much in open warfare for control of our government right now. It's not full on civil war conflict, but it's getting very close to that.
Well, I've been quite open that I am from NZ and it's unclear what you mean here by "Euros", so I'm guessing you're either just being a lazy smart ass or perhaps you don't understand that NZ ain't Europe?
