Yes, *UK* Police
Once the Thin Blue Line in the rest of the UK realises how easy this will make the lives of their English compatriots, they will be falling over themselves to adopt it. Well, the men and women who join up in a desire to make the country a nice, safe for the rest of us to live in possibly not so much, but certainly those holding the purse-strings.
No need to talk to the public any more, just direct them to the online reporting system. So no need to have all those police stations cluttering up the cityscapes, sell them off and put the criminals under house arrest since we've got no cells. And if we can do it for the less-serious crims, then we can extend it to the slightly worse ones. And when that doesn't go too wrong*, we can expand the scope a little further. Then we can sell off all the prisons as well. And build a few new golf courses and country clubs.
*Care in the community is the prime example of this - when it works, it's a good thing. Unfortunately not everybody is able to behave in the manner necessary to live in a relatively uncontrolled environment.
