There was a time when a church was a place of safety or refuge, either by law or by convention, and at times people could "hide" in a church building. They considered themselves safe because no one would commit violence in a "holy" place.
This idea of a safe haven has come under attack both literally, in Texas, and metaphorically around the world. It's not just a matter of who can have guns and certainly not the horrifying suggestion of bringing more guns for more safety. It's a worldwide issue of many people needing a place of safety and a right to be safe.
We have a long way to go till we really feel safe.
