Let's face it, if they really want to, US Government (agencies) can already do WTF they like to anyone, anywhere, home or abroad, and there isn't a thing anyone can do about it. 99% of people just happen to be not significant enough to warrant the effort.
As for people claiming life is better or more free outside the US... where are these utopias? Asia? Latin America? Russia?
The only reason to live in some stinking, polluted, endemically corrupt, backwater police state in Asia or Latin America is if you're too broke to afford putas in the civilized world (where most in the third world would kill to live) and/or you're addicted to tranny cock.
And the only reason to live in Russia is if you're a criminal and/or mentally deranged.
