Yellow journalism - Wikipedia
I watch a lot of different channels for news and usually they are quite professional when dealing with mass shootings. Some channels aren't because they have to fill a 24 hour news day and they just repeat the same stories with small variations. Usually interviews of various talking heads who mostly share the same viewpoints with small variations. They might bring someone in as a counterpoint but that is usually to just make themselves look good in comparison.
There are rifles, shotguns, and the like that should not be sold at all to the general public. Some criminals always get around laws but as far as home defense there are many options available that will work very well. Some criminals will get access to weapons that the general public does not.
And the view of the 2nd Amendment creating some kind of right to create a revolution through arming of men and women of sound mind and with righteous motives, etc., I do not buy that the Founding Fathers wanted that. Roman history is full of armies fighting to put their own emperors on the throne and who work to make themselves rich and powerful off their own connection with this chosen emperor. You get endless civil wars through that or someone who claims to be chosen by God.
