I suppose its a cost/benefit attitude. When the average joe starts to think about actually killing scores of poor schmucks that happen to use a little weed here and there, they lose the will. Or I should say, realize they never had the will in the first place. Yeah, I suppose you could go around whacking citizens left and right, but is the end worth the cost? Fewer people are listening to Pink Floyd? Cheech and Chong rentals are down? Doesn't sound worth it.
So you'd rather continue the WOD as it is now? That ain't working.
