As this article suggests fraud and scam numbers continue to rise especially against the elderly or vulnerable. 

With these scams appearing to be hidden from the public consciousness in such that they tend to happen to someone in their home and can of course go unnoticed by anyone including the victim, there is no public outcry to the lack of frauds solved or money returned to the victims. 

Increasing scam awareness messages can only go so far. Ensuring our elderly neighbours and family are not isolated and vulnerable to such scams again can only go so far. Whilst the nature of such scams are escalating and much of the true levels being under reported it can feel like the fraudsters are winning.  Collaboration between the police, government agencies, charities and the private sector can only strengthen the resolve that we want to see; our members of society protected from such scams and the fraudsters parted from their ill gotten gains.
