SAN BERNARDINO ( — The attack on Wednesday at the Inland Regional Center in San Bernardino was the deadliest mass shooting in the U.S. since the massacre at Sandy Hook Elementary School in 2012.  At least 14 people were killed and at least 17 people were injured.

One of many questions being asked after the attacks is: What exactly does the Inland Regional Center do?
