Police give out warnings and 'tips' all the time for various crimes. i.e lock your doors, do not go to this neighborhood at night, if you see this person call 911 immediately.
Point is criminals will break the law regardless of whether or not we think it's human decency/law/etc not to. Giving people advice on how to further minimize their chances of being a victim is better than them being a victim.
'Be careful how much you drink' vs 'Well it's your fault you got drunk' one is victim blaming the other is advice.
