This guy makes good points, and then muddles them by taking them too far. In the two examples given is basically "don't have these problems in the first place." Which would be great, if it was that easy. Since no one can snap their fingers and make all burglaries go away (even by decriminalizing drugs as he suggests), there will always be a need for some form of policing/intervention. Now, if you could reduce the amount of need for police while morphing them to look e.g. more like London's police like someone suggested in this thread, you could affect real change. But the way he's implying it will go "just give homeless people housing and you won't need any police for that anymore" indicates to me that he doesn't know just how difficult these problems are.
