Для тех кто писал что наличие оружия у людей в России поможет им защититься от преступников.
К примеру исследование в 1998 году на примере нескольких крупных городов в США показало что нпри наличии пистолета в доме шанс что он будет использован против члена семьи в 22 раза превышает шансы что он будет использован против вторгнувшегося преступника.

Guns in the home. The environment that has been studied the most is the home. One study found that the presence of a gun in the home increased the risk of homicide of a family member by a factor of three and the risk of suicide by a factor of five . Another study found that a gun in the home was 22 times more likely to be used to shoot a family member than a criminal intruder . During the study period, for each time a gun in the home was used in self defense or a legally justifiable shooting, there were 7 homicides or attempted homicides of a family member, 11 suicides or attempted suicides by a family member, and 4 unintentional shootings of a family member.
Guns in the workplace. A North Carolina study found that workplaces that allowed workers to carry firearms and other weapons at work were 5-7 times more likely to be the site of an on-the-job homicide compared to workplaces that prohibited workers from carrying weapons . The North Carolina study confirms that just as residents of households with guns are more likely to become a victim of a homicide in the home, workers who work in places that allow guns are more likely to be killed while at work.
Guns and suicide. A study by the Harvard School of Public Health compared gun suicides with non-gun suicides in the15 states with the highest rates of gun ownership with the 6 states with the lowest rates of gun ownership (using only 6 states such that the populations of both groups would be approximately the same). During the five year period 2001-2005 there were approximately four times as many gun suicides in the high gun ownership states compared to the low gun ownership states (16,577 vs. 4,257) . Non-gun suicides in the two populations were approximately the same (9,192 vs. 9,259).
More guns will result in more fatal suicide attempts
Suicide is the second leading cause of death for college age young adults, exceeded only by accidental death (mostly from motor vehicle accidents). On average, about 1,000 college students commit suicide each year while another 24,000 attempt suicide. Whereas suicide attempts by overdosing on drugs (the most common method) are fatal only about 3% of the time, suicide attempts with firearms are fatal more than 90% of the time. It goes without saying that making firearms more available to college students will make it more likely that more of these 24,000 unsuccessful attempts each year will be fatal.
