Why do the shootings keep happening?

Yesterday in Texas, right after shooting his grandmother, a man went to an elementary school and began shooting at the kids. Summer vacation was almost here. Yesterday was the second to last day of the school year. At least 19 children were killed. How could this happen? Why?

Earlier this month there was a massacre at a supermarket in Buffalo, New York. The next day a mass shooting occurred at a church in California. Add to these the long list of mass shootings at various places across the US. There was the 2017 Las Vegas shooting that claimed 60 lives. Remember too the Orlando nightclub shooting in 2016 where 49 people were killed. In 2007, 32 were killed at Virginia Tech. Twenty seven lives were lost at the Sandy Hook Elementary School shooting in 2012. This is only a partial list. The shootings keep happening.  Why are we willing to live with this carnage?  Why?

Why is it easier to buy a gun than to get healthcare for the bullet wound? What is the answer to this gun violence? Does anybody care? Why do the shootings keep happening? Look at the rest of the world - mass shootings aren't happening anywhere else? How come it keeps happening here? Oh and can somebody explain this open carry thing? Seriously. There are 42 states that allow for open carry of some or all firearms. I'm from California (where that is not allowed) and I just don't understand why someone needs a long-gun when they go pickup their coffee at Starbucks. Why?

Last night, Golden State Warriors coach, Steve Kerr asked an important question: "When are we going to do something?" I wish I had the answer. I am convinced that something can be done, so why wasn't anything been done yet? Why?
