Note, we aren't talking about mass shootings between gangs or criminals That's an occurrence that has been happening for generations. Lets not go away from the topic at hand.
What we are talking about is random mass shooters, people shooting at schools and other areas where innocent people are at. This is the new phenomenon. The rest hasn't been something that concerns anyone, if so Chicago and Baltimore would have been militarized because of their violence issues.
Mass shootings are mass shootings no matter who they're between, and I don't see why anyone would object to making a concerted effort to reduce them, because the stats for anything relating to guns are frankly shocking for a supposed developed country. Since it doesn't seem to be accepted at all I'll remind you again: it does not happen in any other developed country, even ones with significant problems with their culture and govts that largely aren't fit for purpose.
Mass shootings do happen, as mentioned by Aaron, south of the border. Between the Mexican cartels. They kill each other every day.
Back when Colombia had their guerilla wars, they killed among each others.
In Africa, till recently they had war in Ethiopia. In the middle east, they had ISIS, recently Yemen. Now in Europe there are mass killings too with the Russian invasion of Ukraine.
In Europe they are a rare occurrence but they do get their share, mostly among gangs, and very rarely random, but they occur.
People kill each other everywhere, just for different reasons unfortunately.
Many of the killings happening every day barely get any mention. In El Salvador, Guatemala and Honduras killings don't even get mentioned by the local press.
Killings in the US do get the attention, perhaps that's why so many random mass shootings happen, so that these people get the notoriety they see on TV. That may be also part of a reason.
I hate mass shootings even if they are gang related, just that noting the mass shootings in the inner cities of the US is something not big of a deal for the MSM and the political left. But I agree, they are as bad a random shootings.
The issue at hand with the random shootings, are like I have said many times, A new phenomenon that has began since the 90's. The government can't control the gang killings, but we tend to think they can control the random shootings. Perhaps if they focus on mental health issues these random shootings will decrease.
