On an individual level of the victims and their families, it is terrible. There is a heartbreaking video on social media of a 50 something father who broke down in tears because he felt guilty about not doing more to stop the shooter because he wanted to save his son instead.
On a national level though, it is hard to sympathize. My understanding is that a majority of Americans want greater gun control yet they voted republicans back into the senate who will do nothing but dance to the NRA's tune.
They voted for a president who they knew would do nothing about gun control despite an alternative candidate who promised to address the issue.
So there will be the typical CTRL+C, CTRL+V from the last mass shooting. They'll be thoughts and prayers, democrats will demand action, republicans will say it is not the time and the 2nd amendment must be protected, the news cycle will move on but there will be another group of families forever changed and scarred, and then repeat, and repeat and repeat.
