Multiple mass shootings across the U.S. leave at least 6 dead on holiday weekend | MPR News:

A spate of weekend mass shootings and violence across the U.S. killed at least six people, including a Pennsylvania state trooper, and left dozens injured.

The shootings follow a surge in homicides and other violence over the past several years that experts say accelerated during the coronavirus pandemic. They happened in suburban Chicago, Washington state, central Pennsylvania, St. Louis, Southern California and Baltimore.

"There's no question there's been a spike in violence," said Daniel Nagin, a professor of public policy and statistics at Carnegie Mellon University. "Some of these cases seem to be just disputes, often among adolescents, and those disputes are played out with firearms, not with fists."

Researchers disagree over the cause of the increase. Theories include the possibility that violence is driven by the prevalence of guns in America, or by less aggressive police tactics or a decline in prosecutions for misdemeanor weapon offenses, Nagin said.

This problem is uniquely USA, let’s question the last statement…

• "prevalence of guns in America" - The growth in mass shootings tracks with the growth of gun sales, and in this we're alone in the civilized world.
• "less aggressive police tactics" - This seems to be limited to white males, but even with changes our law enforcement is the most aggressive and combative among civilized nations.
• "decline in prosecutions for misdemeanor weapon offenses" - This seems to also be limited to white males, and is accompanied by Stand Your Ground and Concealed Carry laws where Some People can literally get away with murder. This is another place we're alone in the world, because in most countries gun ownership is severely regulated and offenses around ownership tend to be vigorously prosecuted.

So what’s different here? Too many guns.
