It's not victim blaming to tell people not to take risks. Is it victim blaming to tell someone not to leave their handbag on a cafe table while they go to the loo? No - it's telling people to protect themselves and show basic sense.
Lots of people walk home alone at night, but when you're hammered, all sorts of crazy things seem perfectly logical, including a long walk home alone on a questionable route that you would never normally take through the weird part of the city centre when you're wearing ridiculous heels and weaving about all over the place, because your phone's dead and you can't call or afford an Uber/taxi.
I remember walking home from town one night as a teen on a silent city street, with cars/vans parked along the side I was walking on. Out of the corner of my eye I saw a guy unnecessarily cross the road and start walking closer and closer behind me. I got spooked, and went and walked in the middle of the road where I could be very clearly seen from all around. The guy walked on. Maybe it was nothing, but I didn't FEEL like it was nothing at the time. If I'd been drunk though, I would have been wearing headphones blaring out Nine Inch Nails and completely oblivious to any risk.
There is nothing victim-blaming about encouraging basic gumption.
