The New York Post does not see this as a conservative or liberal issue — it’s an issue of life and death. Curbing guns is what led to New York City’s three-decade reduction in murders. And, sadly, it’s the dismissal of that progress that has led to a rise in shootings here. Outside the city, the toll of semi-automatic weapons is a sad litany of cities and schools: Newtown, Parkland, Aurora, Las Vegas. It’s a national shame.

We called on President Donald Trump to act, and we’ll happily support Biden in a fight for the needed changes. Polls show most Americans want this. It’s the political establishment that is frozen.

Wait! shouts the “do nothing” crowd: The Atlanta and Boulder killers used handguns, and both seem to have major mental-illness issues. How does this justify drastic action?

In fact, the Boulder gun was an AR-15-style weapon with a pistol stock and a shorter barrel — less accurate, but easier to conceal — and nothing that any civilian needs to own.
