I guess I'm not be reading the same type of science fiction.

You contact NASA because you found a meteorite with clear signs of alien life, a black helicopter will pick you up, you get put in a dark cell, interrogated, and then told to forget all about it or G-Men will disappear your family. You try to sell the news to mass media, but rumours start to spread about you. Your life work get discredited, you lose your job and family, end up wandering the streets in an alcohol daze muttering about aliens.

I guess it depends if you've drank the kool aid about the US government being the good guys, or not.
