Lott mentioned that, “Depending upon the state, anyone from a family member, intimate partner, ex, house or apartment mates, or police can file a complaint.” That is scary enough; if an ex or even an angry or jealous family member wanted to, they could file a complaint. But we now live in very fluid times. Sue, a friend called me last week and related what had happened to her. Her daughter, Kerry, left a frantic text message that she needed her to come right away. Sue called Kerry to find out what was happening. Kerry was at a minor-league baseball game, enjoying herself and had no emergency. Sue called the police who told her that there is an app you can get that lets you use other people’s phone numbers. It happens that Kerry has a bit of a stalker situation at her work and she suspects that he is the one that made the call. But as the police told them, there is no way to trace who made the call.
I can easily imagine someone like that Red Flagging her. Or, there is another scenario I can imagine happening (and I don’t have much of an imagination or I’d be writing fiction and selling lots of books). That is someone(s) wanting to break into your house to rob you or worse, do to you what those men did to Carolyn Warren, above. With such open Red Flag laws, they can disarm you by cop. This isn’t farfetched. The police would take your guns and, by the time you got the situation rectified, you might be dead.
