Well, I'm not really advancing an opinion as to whether the article is a problem or not. But looked at it, it is a fairly mundane description of a radio station right in the heart of France. I struggle to see how any interpretation of the content could be a direct threat to soldier or civilian lives... so your rhetoric there doesn't sit comfortably.
I for one think that the following, "ends justifies the means", approach is not acceptable; "Trust us, we're the government and though it looks innocuous it is threatening lives right now. So we will take any measures to remove it". If it is that much of a risk I feel they should be able to convince someone of that fact without divulging the exact problem.
Through all of this the intelligence agency have apparently failed to communicate this sort of urgency, in private, to either a trained lawyer or the sysop in question. Indeed, the legal team quite clearly suggest they made no effort to convince them of such an urgency.
In either case, had they done so, then both would have been able to explain how to quietly remove the article without this sort of Streisand effect...
All of which still does not excuse the fact that they threatened a private citizen with terrorism charges.
> I sadly would trust the gov't on this decision than an individual.
I feel that what is often forgotten about govt. is that they are made up of individuals. What you are actually arguing here is that of the several individuals involved, some of them presumably have more information (i.e. secret govt. information) than the others.
