I think if anything needs to happen, they need to make it easier for ordinary citizens to protect themselves. It would have only taken one armed good guy in there to avoid this many losses. Bad guys are always going to find a way to get their hands on guns, and when they do, the first reaction is to call for more restrictions on legally owned private firearms. Maybe the tone will change once an ordinary citizen who happens to be carrying takes down one of these psychos before they can cause this much damage .
Happens more often than you think, you just never hear about it because our society thrives on the bad. “It aint news unless it’s horrifying” mentality. Sickening.
