So you're expecting a stupid low life pimp to risk serious time killing a john in an apartment where foresnics, cameras, and eye witnesses are everywhere? No. They are expecting you to be week and just give up your cash freely without a fight.
I get it. If you're old, you don't want to tussle. But if you're in good enough shape and out power this piece of shit, call his punk ass out.
That's brave talk, but you've missed the point, and spelled "weak" incorrectly. Probably wouldn't be much of a challenge to sort out the handler with the proper mindset and tactics. Remember that you may be in front of a judge explaining everything. If you demonstrate intent you may go to jail for your heroic deed.
The main point, though, is that the handler will seek revenge on the girl. She'll be the victim. Your brave talk and bravado may get her injured, or worse.
The above scenario happened to me. Was bicycling through Downtown late one night full of beer and bravado. A pimp chirped me about my bicycle, I told him to get a life. He sprinted across the street after me and caught up fast. Showtime.
Put the bike down and waited for his weak-assed shit. Was about to teach the Thug some manners when the girl got between us, begging me not to fight her man, screaming "he'll kill me." She dragged him off into the night. Lesson learned. Girls are targets for the handlers.
Approach meets with a tactical eye. Don't remove clothing until the girl does, and if she leaves be clothed and ready.
It's easy to pick out who has formal military and/or fight training here and who doesn't. Some grasshoppers chirp too much and have much to learn.
Still doesn't solve the problem of how to help Alyssa get rid of the Untermenchen.
