Plus we have a birthday coming up!

And not to forget A Night to Remember, 15 April 1912, when RMS Titanic met her end.

From tragic to absurd, occurs tax evaders don't much love April 15 either.

But then there is also the midnight ride of Paul Revere ("'Twas the 18th of April in '75,/Hardly a man is now alive/Who remembers that famous day and year.")

NBC seems to concur:

April 15, 2013: Three die when two packages explode near the finish line of the Boston Marathon, injuring more than 100 others.

April 16, 2007: 33 people are killed on the campus of Virginia Tech when a gunman opens fire.

April 19, 1995: 168 are killed in Oklahoma City when Timothy McVeigh drives a truck filled with explosives into a federal building.

April 20, 1999: Two students at Columbine High School near Denver open fire on classmates, killing 13 before turning guns on themselves.

The tragic deaths in this week at the end of the Boston Marathon occurred on April 15, tax day in the United States. Monday was also Patriot Day in the Boston area, a day commemorating battles that began the Revolutionary War.

As a month, on the surface, it would seem April sees a disproportionate number of violent episodes in the United States.

A report this week on NBC's Today show pointed out the volume of tragedy experienced by the nation during the fourth month of the year. Reporter Tom Llamas showed repeated acts of violence - some terrorist attacks, some school shootings - that have happened in April over the last 20 years.

Llamas says April has become "a painful and unforgettably violent month in this country's history."

So the Ides of April. As with Rome's Ides of March, doth this portend our transition from the U.S. Republic to the U.S. Empire? Or worse -- ref. recent threads on Constitution, Shredding of?
