Despite the popular image of terrorism as bombings alone , and the large number of casualties and higher media impact associated with bombings , conventional firearms are as much if not more pervasive in their use . For example , in the second part of the 2011 Norway attacks 68 people were killed by Anders Breivik , a man armed with two guns . The 2008 Mumbai terrorist attacks were done partly by guns and partly by bombs . Also , one Transportation Security Administration officer was killed and few others injured by a man with an assault rifle in the 2013 Los Angeles International Airport shooting
