Exactly who is she calling an asshole - the coward police officer who refused to enter the school, or the police who visited his house dozens of times without doing anything, maybe the sheriff more concerned with faking his numbers rather than doing his job, or the FBI who dropped the ball or maybe even the actual deranged shooter? Nah, she's calling you and I the asshole, along with the NRA and all Republicans. In her confused and deluded mind, it's our fault.
