The details of the tragic Sunday shooting in Boulder, Colorado, that left 10 people dead are still being discovered. But we do know that the gunman, who opened fire in a grocery store, reportedly used a semi-automatic AR-15 rifle and that Democrats are immediately using the tragedy to renew their push for gun control.

This horrific shooting has drawn particular focus to proposals for an “assault weapons” ban over other forms of gun control due to a set of unique circumstances. The city enacted such a ban in 2018, yet it was struck down as illegal by a state judge last week. Democrats are thus responding by renewing calls for the ban, assuming it would’ve prevented the tragedy even though many other firearms not covered by bans on “assault weapons” are capable of essentially the same firepower.
