A lot could have happened: she may have fumbled with a safety, she may have thought a round was chambered, she may have experienced tunnel vision under stress, and the list goes on. This is an example of why we should advocate against plans to tax or limit ammo. It needs to be cheap (preferably tax-free). We should advocate for incentives for citizens to move beyond one-eyed target practice and into tactical shooting practice. The tough part is making a stain out of someone and leaving that haunting feeling in a home that you built and cherish. Lucky it was a good outcome.. and I do mean "luckily" for both the homeowner and the creep.
