The Annotated Homicide Rate VS Gun Control, 1885 To 2011
A couple of recent key points:
6.) The Second American Gun Control Drive The second
gun control drive effectively began in early 1963 and the results were
immediately obvious. Homicide rates doubled in a decade, going from a
rate of 4.6 per 100,000 population in 1963 to an official rate of 9.4 per 100,000 in 1973 and 9.8 in 1974.
The apparent short term declines between 1973 and 1991 are a result of
under-reporting crime totals, and not an actual decline. That decline
did not come until…
7.) Relaxed gun laws and
falling crime rates By 1991 the beneficial effects of Florida’s
Concealed Carry Weapons permit system had become obvious. The two
murders a day in Florida’s roadside rest areas had disappeared, violent
crime and homicide rates were “falling off a cliff, and people sorely beset by violent crime were begging their legislators for relief. And for concealed carry.
