The problem is - despite the media coverage - gun violence is down massively over the last 20 years.If outrage over mass shooting gets people to take a look at gun laws and say--here's something that might help--whether it's new laws or better enforcement of existing laws or better screening for mental health problems--that's a step in the right direction.
People are outraged over 'mass shootings', yet nearly every weekend, ~50 people are shot and about 5-10 of those die in a city with some of the most restrictive gun laws in the US (Chicago). I don't hear a lot of outrage about that.
