The killing of at least 12 people at a midnight screening of The Dark Knight in Aurora, Colorado is the latest in a long line of tragic mass shootings in America.
Aurora is within 20 miles from Columbine, Colorado, where two teenagers opened fire at their school, killing 12 schoolmates, one of their teachers and themselves in 1999.
It comes five years after 32 people were killed at Virginia Tech campus, the Washington DC sniper attacks and 2011's incident in Tucson, Arizona where six people, including a young girl, were killed and Congresswoman Gabrielle Giffords was shot in the head at close range.
