Regarding the USCCB and their opinions on gun control, they really add nothing to the conversation beyond implying that their positions are somehow more moral than the opposing ones. For a less stale look at the problem, however, we might consider this as an alternative:
Though we seem to be plunging ever deeper into a dark night, researchers now have a far clearer view of a key factor in the violence. A long-standing theory has matured into a body of evidence that can no longer be dismissed: The level of attention paid to mass shootings is central to why they keep happening.
The idea that some crimes might be self-spreading, like a disease, was proposed as early as 1890, when the French sociologist Gabriel Tarde labeled murders copying Jack the Ripper “suggesto-imitative assaults.” For mass shootings, the effect was well known among researchers by the early 2000s, when a wealth of information allowed forensic psychiatrist Paul E. Mullen to conclude, “These massacres are acts of mimesis, and their perpetrators are imitators.” (Essay by Ari Schulman, Wall Street Journal 11/18/17)
Perhaps instead of trying to control those who are not contributing to the problem we should find ways of dealing with those who are.
