If you were to take a walk in lower Manhattan, in New York City's bustling financial district, between the intersection of Wall Street and Broad Street, they may not notice something peculiar in the side of one of the city's most prominent buildings.  Ranging in size from small, missing chunks of limestone to deeper, baseball-size pits, the J.P. Morgan building's stone façade is scarred with pock marks - a constant reminder of one of the city's, and country's, greatest terrorist attacks of the 20th century.  But this wasn't the result of shrapnel from the 9/11 attacks that gripped our nation in 2001.  This was damage inflicted from an oft forgotten attack earlier on, in September of 1920 - one in which the J.P. Morgan building was never repaired from and one in which an assailant was never convicted.
