Maine mass shooting marks America’s 565th this year – and the deadliest

So far, 2023 is expected to be the deadliest year on record for mass shootings in the US

America has been rocked by another mass shooting after authorities say a gunman opened fire at a bowling alley and a bar in Lewiston, Maine killing at least 18 people.

Thirteen people were injured in Wednesday night’s shooting. It’s the latest massacre in a year filled with mass shootings like it.

At least 18 people have been killed, with the Lewiston shooting expected to be the deadliest shooting to occur this year.

It is the 565th mass shooting to rock the US this year, according to the Gun Violence Archive, which classifies a mass shooting as any time four or more people are shot or killed, not including the perpetrator, in the same location at relatively the same time.

Like many years before it, 2023 has been marked by mass shootings in public shopping centres, neighbourhoods, schools, private residences and more.

Here is a list of some of the prominent mass shootings to occur this year.

Nearly every US state allows gun owners to carry concealed weapons in public in some form. But more than half of US states allow most gun owners to carry a concealed firearm in most public spaces without a permit, background check or safety training, as Republican lawmakers advance a so-called “constitutional carry” movement through state legislatures.

State officials later moved to ban assault weapons and high-capacity magazines like the one used in attacks in the last 10 months. But assault weapons like AR-style rifles remain widely available across the country, despite repeated demands from President Joe Biden and widespread support among Democratic members of Congress to reinstate a federal ban.

Since taking office, the president has had more success in enacting new gun safety legislation than any president since Bill Clinton’s two terms in the 1990s.

But with a Republican-controlled House of Representatives and a de facto 60-vote threshold for any legislative action on any matter in the Democratic-controlled Senate, it is unlikely that Congress will make any progress towards any new laws that would restrict the availability of firearms in the US – even as a majority of Americans believe it should be more difficult to get them.
