that is what a talking head said and she was right. Many Americans no longer even want to hear about them or do not look up t their TV from their phones when they are being shown on the networks. Pretty soon the old saying will change to mom, apple pie and mass shootings. And nothing, and I mean nothing will be done o stop them. It is a sickening truth, but there it is, guns are more important than children.
The issue is more complicated, though. When you say 'gun' to a Republican, they picture themselves protecting their child with the gun, and defenseless without it, and think Democrats want to leave them without protection. The anti-Democrat propaganda is strong enough that most of them are against any safety measures from Democrats, and it seems there are no safety measures from Republican politicians.
Further, I don't know any policy Democrats support that would prevent mass shootings. There are some policies that might mitigate some - might prevent a few of the sales, might make the guns kill a bit more slowly, but no policy being considered would prevent mass shootings.
So that makes the debate more one of a debate about 'attitude' - with Republicans more enthusiastically supporting gun rights and their response being harsh punishment for mass shooters, while Democrats more loudly criticize mass shootings but their solution is to just take minor measures that leave most of them happening.
Even if Democrats decided strong gun control was a good idea, there are practical issues now that our society is smothered in hundreds of millions of guns. In other words, this isn't really like, say, Voter ID laws where Democrats might have a solution, but rather is more Democrats criticizing the problem but not having much of a solution, just a few improvements.
And you're also right, that the nature of news and media is that as both the mass shootings are large in number and people aren't that interested, they're likely to not get much coverage. 'News' is for stories that get ratings. When mass shootings are like plane crashes they're covered, when they're like car crashes they aren't. So 200 killed in a rare plane crash is news, but 1,000 killed in car crashes daily isn't covered.
