"the theory underlying gun buybacks is badly flawed and the empirical evidence demonstrates the ineffectiveness of these programs."But I also saw this point:
Advocates may think that getting rid of weapons will at least prevent accidents and suicides. But some people who hand over a gun will hang on to other guns, which they are just as likely to handle carelessly or leave where a child can find it.Furthermore, here are some stats on overall murder rates in major U.S cities.
As for suicide, the odd thing about people intent on killing themselves is that if a firearm is not available, they can find plenty of other methods that will serve their purpose. The National Academy study said that "gun control policies may reduce the number of gun suicides, but they have not yet been shown to reduce the overall risk of suicide in any population" (my emphasis).
