Often a stalker is way ahead of their target eskie. They look for certain things in their target that they have learned in their own stalking practices that they can manipulate and play around with psychologically. They also tend to get good at practicing these games under the radar where they even appear to be a "good" person who looks like they respect others and can be trusted. They know how to camouflage themselves really well and it's not unusual for them to have a group of individuals around that like and respect them either. So, when they target someone they have their groupies that they know won't believe their victim and not only that but they can actually convince their groupies to also attack their victim. They can learn how to slither away like that homecare person you mentioned where they avoid facing being held accountable too.
