FOR those of us who argue in favor of gun safety laws, there are a few inconvenient facts.

We liberals are sometimes glib about equating guns and danger. In fact, it’s complicated: The number of guns in America has increased by more than 50 percent since 1993, and in that same period the gun homicide rate in the United States has dropped by half.

Then there are the policies that liberals fought for, starting with the assault weapons ban. A 113-page study found no clear indication that it reduced shooting deaths for the 10 years it was in effect. That’s because the ban was poorly drafted, and because even before the ban, assault weapons accounted for only 2 percent of guns used in crimes.

Move on to open-carry and conceal-carry laws: With some 13 million Americans now licensed to pack a concealed gun, many liberals expected gun battles to be erupting all around us. In fact, the most rigorous analysis suggests that all these gun permits caused neither a drop in crime (as conservatives had predicted) nor a spike in killings (as liberals had expected). Liberals were closer to the truth, for the increase in carrying loaded guns does appear to have led to more aggravated assaults with guns, but the fears were overblown.

One of the puzzles of American politics is that most voters want gun regulation, but Congress resists. One poll found that 74 percent even of N.R.A. members favor universal background checks to acquire a gun. Likewise, the latest New York Times poll found that 62 percent of Americans approved of President Obama’s executive actions on guns this month.
