Should we worry about April 19th?

Before 9/11, there was 4/19.  At about 9:00 am on April 19th 1995, a huge explosion leveled the federal building in Oklahoma City, killing 168 and injuring a lot more.  The casualty included children who were in the daycare facility.
This was no result of any clash of civilizations, nor did it bring about any question of why do they hate us.  Because, it was the rarely ever discussed home-grown terrorism.

The Alfred P Murrah building in Oklahoma City was bombed at 9.01 in the morning, as a normal working day on the Great Plains was getting under way – not by Islamic fundamentalists plotting in Afghan caves, but by a paramilitary unit of Americans who called themselves "patriots", led by a former serviceman and 1991 Gulf war veteran, Timothy McVeigh. McVeigh was executed in 2001, and his principal accomplice, Terry Nichols, is serving life.

Here is the horrible coincidence: it is on April 19th that the Tea Party folks will be holding their protests all across the country.  So, let us see: people upset with taxes--which are due on the 15th--more so during this Great Rececssion; people upset with the recent healthcare reform; people worried that the government is coming after their guns; Faux News whipping up hysteria at the drop of a hat; Jihad Janes; .... and national protests are on the 19th?  Seems like a horrible lining up of the planets.
Remember Arlington Road?
