Letter to the editor: Proposition Q, a controversial measure on this year’s ballot, would prohibit the ownership of handguns within the city’s limits. Under the plan, gun owners would have a 90-day grace period to turn in their weapons to authorities. Proponents of the proposition argue that fewer handguns on the streets would lead to less violent crime, making the city safer for all of its citizens. Unfortunately, the ban would actually have the opposite effect. Since only law abiding citizens would honor the ban, armed criminals would not only keep their weapons but would also have the confidence to act with impunity on a population that could no longer defend itself.
