It should be MUCH more expensive so that players still make use of /bribe. But then players won't use it much, making the effort scripting this wasted. I do like the idea, though.
Whilst we do have bribe pickups, there is a time limit between using them.
I'd support Lester being an option players can use to reduce WL by 1/2 stars for money (balanced: player will be stationary at payphone, giving a nearby $cop chance to apprehend them).
