I would expect drunk-driving deaths to far exceed firearm homicides, and it's honestly shocking that firearm homicides are that high. I think the stats show that it's not blown out of propertion.
The problem is an underfunded systems and huge workload and a bit of funding would instantly safe more lives than restricting gun ownership.
Calling for restriction is a transparent political move or is born out of ignorance in my opinion (I am not from the US).
People that would profit the most from restrictions are policemen, which are probably underpaid in the US considering their risk.
I know that these numbers are not directly comparable, but given the deadly nature of automobiles in general, I expected drunk-driving deaths to be somewhere around 50000 per year.
