Requiring comprehensive, universal background checks on all gun sales would help prevent gun violence in Wisconsin.
- In Wisconsin, federally licensed dealers are required to conduct a background check on all firearm sales, but private sellers are not. This private sale loophole allows just about anyone to sell a gun with no background check, no identification, and no questions asked. Between 80% and 90% of Wisconsinites, including gun owners, support background checks on all gun sales.
- In the 10 years following Connecticut’s passage of its law requiring prospective handgun buyers to first get a permit – by passing a criminal background check – firearm homicides declined by 40%.
