"We need to recognise that the crime prevention challenge has evolved – we now need to prevent serious harm that happens inside victims’ homes, or to stop a cyber-criminal on the other side of the world from targeting thousands of people here with a single keystroke."
Sadly, this will likely do nothing to prevent the most common crime that happens in people's homes - domestic violence. This is one of the most under-reported crimes, and unless you have been a victim (or a perpetrator), you would likely think that it is much less common than it actually is - astoundingly one in twelve women is a victim of some sort of domestic abuse every year (and yes, it does happen to men too).
What we really need is a cultural change towards acceptance of violence of all sorts in our society, be it the public brawl on the high street on a Friday night, or the more insidious violence that happens behind closed doors, and this is an area where predictive policing could really help. If a woman is in a new relationship with a partner who has a record of violence against other women (a common pattern of domestic violence), it is not beyond the realms of possibility that this link can be identified, and the woman warned.
I doubt, however, that this programme will help in this way. It'll probably be politically led, looking for the vanishingly small number of terrorists under every stone, whilst ignoring the real crimes that actually affect people's lives every day. It'll be target-led, leading to easy to solve but low impact crimes (like littering,or parking on double-yellows) skewing the system.
