I like the serial killer idea. Of course, I think more than two or so enemies would be needed in a game, to balance the action a bit. I suppose you could have the cop you controlled respond to other things as well (such as calls for backup) which might or might not be linked (more not linked than linked, so it doesn''t feel too set up).

I haven''t seen the original Day of the Jackel, but I thought the American version was quite good. I think that''s what there trying for with Hitman 2.

I suppose that if you were worried about not having enough action until the end, why not have a small group of targets to be taken out one by one. The film that comes to mind along a similar theme is Blade Runner.
