They've been lying for a while now bro.
They lied about the bailouts, the economy, 9/11, osama, the "nukes" in Iraq etc. etc. Heck it even gets into food, health, family life ... it goes pretty deep if you believe it.
It's all about power. This particular lie is for taking away guns as warned by the guys who founded America and began this short and soon to end age of freedom.
"A free people ought not only to be armed and disciplined, but they should have sufficient arms and ammunition to maintain a status of independence from any who might attempt to abuse them, which would include their own government."
The goal is the usual, domination, manipulation, empowering a few while impoverishing the rest... stuff that has happened throughout history, and it's coming knocking again. Governments getting too big, too powerful, too corrupt and too selfish.
I would suggest look up videos and articles on independent media about these things I mentioned and go from there. Be discerning though and check facts yourselves from links, history etc., there can be lies in independent media or the internet just as there can be truth. And above all stay calm and respectful instead of getting angry, arrogant or ranting about it, because that just pins you as a looney. If you have questions about these things, talk to people you love about them and show them the evidence ... they may think you're nuts at first, but a lot of times they'll come around when they see how blatant it can get.
The point is to keep alert and from being fooled by propaganda, because it probably won't stop here. And just live a better life.
