Mass shootings occur pretty regularly in the US, the thing that fluctuates is the ones where we are sure the victims did not deserve it. So grocery store shootings, church shootings, and the like get treated as special. To be clear, I would like the number of people killed by guns to be zero.
But I am aware we remember to talk about gun violence sometimes, and ignore it others.
One of the mass shootings this weekend involved a Civil Rights activist who had, among other things, taken the time to write about gun violence last year.
If the news has angered, enraged, or saddened you, consider looping into local violence interruption efforts and looking at what kind of support they need. Sometimes it's money, sometimes it's letters written to local electeds to tell them you support such efforts.
