Quick hypothetical situation:
It's 2007. A Muslim (or Black or Latino man) comes to an event at which President Bush is speaking and stands along the route the President is expected to travel. He holds a sign which endorses violence against political leaders. On his thigh is a holstered firearm. What happens?
If you think for one second that the end result mimics what happened to William Kostric, the white man who did this Tuesday, you're simply delusional.
Now the reality. 2008: Mr. Kostric attended a New Hampshire event at which President Obama was speaking, openly displaying his loaded firearm whilst holding a sign that read "It's time to water the Tree of Liberty" (a reference to the Jefferson quote "The tree of liberty must be refreshed from time to time, with the blood of patriots and tyrants"...and I sincerely doubt Mr. Kostric considers President Obama the patriot in this equation).
Was he arrested, charged, prosecuted, imprisoned? None of the above. From footage and reports it's unclear whether or not he was even questioned or observed/followed.
He states that a firearm is a defensive tool (an odd belief in a country with nearly 10,000 homicides by firearm per year). He states that he feels the event would have been safer if everybody attending had a gun. This poppycock is too irrational to event attempt rebuttal.
Now, just in case one think me a tad hyperbolic, peaceful anti-Bush protesters were arrested in Tampa Bay, NYC, Crawford,TX, Charleston, WV, and Kennebunkport, ME (just from a quick Google search). Protestors were also arrested at the 2008 RNC.
And just in case I'm accused of playing the dreaded race card, I'll provide a reminder that although the avowed white supremacists who were captured with rifles in a plot to assassinate then Senator Obama at the 2008 DNC were arrested, no charges were brought against them. Although the very same prosecutor charged an inmate—who just happened to be black—who had mailed a threatening letter containing baby powder to John McCain, stating "we won't stand for threats of this kind in Colorado". Because we all know how much more threatening a black man who is locked down at a penitentiary is than a car full of Neo-Nazi tweakers with rifles roaming about free in public.
There are rather blatant double standards at play here. It sorta reminds me how a Black Harvard professor can be (falsely) arrested for "disturbing the peace" in his own home, while angry white mobs can violently attack a man at a townhall meeting in Florida with no fear of recourse from law enforcement officials. But it's probably just me and my crazy biases overreacting again.
