They may run, or they may return fire. Depends, are they there for your TV like you seemingly assume, or is it a methed up abusive ex here to “take back his kid no matter what gotdammit?” Those two situations are going to be wildly different. Hell, even if they’re here to steal your shit, they don’t always run especially when there’s multiple, you ever hear the phrase “prepare for the worst and hope for the best?” Even if it only happens at the same rate as mass shooting homicides, it’s still something one should be able to prepare for if they so choose.
Gun policy also shouldn’t be based on ineffective feature bans under the pretext of mass shootings when mass shootings would be entirely unaffected. In fact one of the most well known, Columbine, the one all these fucks are copying, only used 10 rnd (or less) mags. It doesn’t effect them at all, the only people who might be effected are those using it for defense who may lack the time to reload becaudr “deadly threat,” so why do it then?
