There are definitely no easy answers. There are undoubtedly more obstacles to accessibility that are easy enough and would unquestionably limit the harm (e.g., the China knife assault today wounded, not killed, 22; sign me up for that trade), but in this political environment where some people are more willing to place blame on Roe v. Wade, it ain't gonna happen.
Pray for the victims, hug your kids, forget the political bs, and hope that the odds are in your favor. Fighting these fights just invariably devolves into more negative energy, which took all of a few moments to happen here. Seriously, there's a reason it's called the cesspool here: it was earned.
