Not all of them, perhaps. But the NRA has a very convenient list of politicians that are friendly to gun rights; which serves as a double-purpose – it’s also a list of politicians who don’t care how big a pile of dead kids it is, as long as they get their backhanders from the NRA.
In the latest tragedy (but hurry up they’ll be another along shortly), the rancid heap of necrotic pus that is the governor (Greg Abbott) tried the usual tactic of blaming mental health despite no evidence the shooter had any mental health issues. The same dude who not only cut mental health funding, but loosened gun controls to make it easier for those with mental health issues to get guns.
There’s a crime that fits the bill – “malfeasance in a public office” – which not completely unreasonably could be argued that certain Republican politicians are guilty of. The ones who take backhanders from the NRA whilst refusing to contemplate any concrete action that might have an effect on mass shootings.
Plus if you threaten them with a scary sounding crime like “malfeasance” they might start contemplating actually doing their fucking jobs.
