What good is it if gun violence goes down while knife violence goes up.
While reducing violent crime is a good goal...
However, gun wounds are far more likely to end in a fatality than knife wounds.
For example a study in The Journal of Trauma (36:4
pp516-524) looked at all injury admissions to a Seattle hospital over
a six year period. The mortality rate for gunshot wounds was 22%
while that for stab wounds was 4%. Even among patients that survived,
gunshot wounds were more serious — the mean cost of treatment for
these patients was more than twice that for stab wounds.
Amusing bit from there:
Thus, if all patients with GSWs instead suffered SWs, there would be an
annual savings of $1,290,000 overall and of $981,000 of public funds from
this institution alone. Treatment costs for GSWs are higher than those for
SWs and are rising more rapidly, with an increasing amount of public funds
going to meet these costs. Considerable savings to society would accrue
from any effort that decreased firearm injuries, even if the same level of
violence persisted using other weapons.
