Sniper attack

Extracted from the Wikipedia article Sniper.
Irregular and asymmetric warfare
The use of sniping (in the sense of shooting at relatively long range from a concealed position) to murder came to public attention in a number of sensational U.S. criminal cases, including the Austin sniper incident of 1966 (Charles Whitman), the John F. Kennedy assassination (Lee Harvey Oswald), and the Beltway sniper attacks of late 2002 (Lee Boyd Malvo). However, these incidents usually do not involve the range or skill of military snipers; in all three cases the perpetrators had U.S. military training, but in other specialties. News reports will often (inaccurately) use the term sniper to describe anyone shooting with a rifle at another person.
