I saw it, and it was brought up again after Santa Fe.
Chicago killings are mentioned, but I agree the coverage is not the same.
The gun ban folks have it wrong.
The do nothing folks have it wrong.
On the gun control side, NRA members are the key. They are okay with some solutions and don't have a problem with responsible gun ownership. Problem: NRA leadership isn't always in tune with their members.
On the people kill people side, if tech companies can collect data and target ads, they can help red flag potential crazies better. Problem: pesky privacy issues and tech leaders are more interested in making money. There was an executive order that made it harder for folks with mental health issues to get guns. For whatever reasons, it was rolled back. If the problem is a mental health issue, Congress could pass a law making it harder for folks with mental health issues to get guns. More money could also be allocated for mental health issues, but it's probably time to work on the recently ballooned deficit now.
Will doing something stop all future gun deaths? Nope. The goal is reducing gun deaths. Baby steps.
