Are you refuting these stats and do you want to provide a source for that?
Also, saying that some gun violence happened so that means gun control doesn’t work is nonsense. It’s like “well some died in a car crash so seat belts and airbags don’t work.”
The facts on this one just aren’t on your side. Looking at this either way - the US is a third world country when it comes to gun violence, and secondarily, countries with relatively little to no gun control have extreme rates of gun violence.
