Could there possibly be a connection.
Ruby Ridge and Waco started with government violence and lead to the Oklahoma City bombing (of which the entire story has not been uncovered).
Maybe the lying, coverups, illegality of the Federal Government especially has lead to a degradation in respect for the law and increased the willingness to engage in violence. Hmmmm?
And finally, the terms "anti-Government" and "Homeland" never used to apply to America, but to unstable 3rd world states. That this now applies is a symptom of the out of control Federal Government, not a cause.
If the is an increase of violence in America, I recommend that Homeland Security look in the mirror for the cause.
Outstanding comments and observation.
