I would have held her at a cautionary distance with a weapon trained on the intruder. If they were unresponsive to talking or me saying "get the eff out of my place" and just standing there staring off, I would call the police while still having my match-built 1911 pointing at aforementioned intruder. If they just hang out and stand there, then whatever. However, if they demonstrate hostility, they are getting dropped by my 230gr jhp friend(s)
