Wife just got back from the magistrates office. They are not going to give her a protective order. They said she couldn’t get one unless she was in immediate danger. To whit she replied, “How many people call ahead and inform their victim they are on their way to kill them?” So plan A was a failure. On to plan B.
Hire an armed security team? If they’re overseas, hire a dozen kids or so to have eyes on the property/car/house with cell phones...
Have your wife conceal carry. Three people in a group at all times, have a private security detail trail this guy and if he gets close, alert everyone.
Install tracking software on kids and wife’s phones.
Move.
Overkill? Not sure.
Just a few thoughts...
