See I kind of disagree (but respect others opinions).
You can't predict this kind of thing.
Her friends were not to know, the students on her street were not to know, the taxi driver was not to know, grey beard was not to know and most importantly Libby was not to know!
What's point saying beware of a stocky guy with glasses flashing his penis?? When there might be a tall, lanky,bald guy likely to do same??
Everyone should be aware and plan their safety unfortunately things like this will happen and they only person to blame is the person that comitted whatever crime has happened.
If it had not been Libby then chances are it would have been someone else.
I feel terribly for her and her family but there are sex offenders all over no point just warning against one!
Be aware all the time of your safety and your awareness of your surroundings.
Not victim blaming by the way she should have been able to go anywhere in any state without harm coming to her but that is not the world we live in
