Abductions by the Government?

Does anyone know anything about people being abducted by the (US)
government? Are there any first hand accounts out there? I'd like to
know more about this. If anyone can help me with providing links, I'd
really appreciate it.

Also, I have heard some people claim that ALL supposed alien
abductions are in fact merely the government abducting its' own
citizens. What exactly would be the purpose for this?

Are certain people more prone to get abducted? One thing I've read
somewhere long ago was that often, many children who lived on military
bases have been found to have been abducted (easy access.) I used to
live on a base (well, 2 different bases actually) and I have been
abducted. (I only remember one time... but I'm sure it's been
happening all my life.)

Anyone have information to share?

*update*
I've been listening to a lot of experts in the field about this topic and they all seem to be saying the same thing. Those HUMONGOUS triangle shaped crafts are our military and those are the crafts used to abduct people by our own government.

I'm thinking that it also might have to do with blood type (which warrants it's own thread, I think). But in short, I think most abductees have a negative RH factor. The government has been trying to clone O- blood type but it is not possible.

I guess they're still doing testing on us.
