Anyway, about a decade ago, Distrigas, the company that owns the facility in question, ran several *military* -- not law-enforcement - -- anti-terrorism scenarios to see exactly what would be needed to take the place out. What I've heard, albeit second-hand, is that in order to get a useful amount of that halfway-to-absolute-zero natural gas actually *flammable*, much less explosive, someone would have to ring the whole tank with a *huge* amount of explosives themselves,
I'm no big fan of science by press release, but when's the last time you heard of anyone saying "Well, we looked at our security situation, and two teenagers with bottle rockets could set this thing off. That's why the CEO has decided to move out of town." The usual response after you've pointed out a devastating attack on someone's system is "yeah, but who'd think of that" or "but you're being unrealistic--real attackers will do this other thing (that we just happen to have defended against) instead."
Cheers, RAH
