　　One of every 10,000 Americans will be murdered this year. More Americans were murdered from 1970 through 1974 than were killed in Vietnam (越南). Since 1990, more than 800,000 American civilians (平民) have been killed by gunfire—more than the total number of casualties (伤亡) in U.S. wars from the Revolution to Indochina.

　　Two-thirds of all murders in the United States are committed (犯罪) with guns, 92 percent of them handguns. Murder rates are highest in these parts of America with the largest percentage of gun owners, lowest in those with the smallest. Since 1968, the murder rate in the United States has more than doubled.

　　These statistics (统计数字) were culled (拣选) from Dr. Donald T. Lunder's recent monograph (专论), Murder and Madness (available) from the Stamford, Calif.. Much of what he reports has been noted before by others, but rarely if ever has anyone probed so comprehensively (综合性地) the American way of killing.

　　As a psychiatrist (精神病学家) who has worked in the police-court-prison system, Lunder notes that the average murderer today is only 20 years old, that 94 percent of all murders are intra-racial, that when they are not, blacks are more often the victims (受害人) of whites, that less than 30 percent of murder victims are strangers to their killers, that the South has the highest murder rate (3.6 per 100,000 that same year), that most murders are committed with little or no planning, that most murderers are easily apprehended (逮捕) and readily confess. (承认)

　　In the majority of homicides (杀人者) the killers had been drinking before hand. Since most homicides arise in the context of a quarrel and involve the most readily available weapon, it is worth surmising (猜测) what would happen if guns were not readily available. Knives—now the second most common weapon-would presumably (大概) become the most likely weapon in the typical assault (袭击) between spouses, lovers, neighbors, etc. In fact the death rate for all victims assaulted with guns is as much as five times that of those assaulted with knives.
