If a co-worker of my wife called in the middle of the night and threatened to rape her in our home I'd just call the police, let them deal with him. If they suggest to leave the home, so be it. Chances are they're going to send an officer to your home so you can file a report first and foremost (while also securing your safety), and in the meantime they would go and locate him.
But no, you called your friend who is head of HR where she works, filled her in, so that when he shows up for work next, security will be waiting.
.. and then proceed to leave and head to a hotel.
Stupidest thing i've ever heard. You're going to let HR and her works security deal with this guy rather than the police, after he called and threatened to rape your wife in your own home.
Are you ****ing stupid
ROFL a
