Val--

I think I can answer your questions simply by saying that the government is not as cautious as you think about promoting an "invasion" fear in the public. Look at the terror alerts that the US gleefully employs. Talk about promoting panic! I don't think that an "alien visitor found" would cause a panic. Who's to say that it represents an invasion? And even if it did, what would you do? Would you leave the place you were living? Would you build a bunker? What?

No, the reports that the government want to simply "pacify" the public are greatly exaggerated by nutsos who really DO need to be pacified because they end up working sane people into a frenzy too. Of course it looks to them like the government is trying to avoid people knowing the truth to stave off a panic, because every person they talk to is trying to get them to calm down!
