This seems to be one of the most common logical fallacies, especially in politics. I dont know if it has a name, but I call it "qualification without quantification". It creates a logic chain that could happen, without any discussion of actual probabilities or costs. For example banning of assault rifles, discusses how it could save lives. People are surprised to learn that there are less than 200 deaths per year from any type of rifle. The same goes for universal background checks.
