I don't doubt that at all. The point remains, however: If the public want peace officers that are afraid to use force, give them that. I'm not risking prison time for people that will vilify me if I use force in their stead, and I would applaud every law enforcement officer that made the same decision. They don't want lethal force used? Okay by me, but they should be prepared to pay the price.
Edited to add:
Thinking about this some more, the initiative is in direct opposition to Graham v. Connor. The language in the decision said the court must view it from the point of view of the officer on scene instead of hindsight and must consider the fact that officers are required to make split-second decisions. This initiative doesn't abide by that.
Really, if it passes I think this thing will be so tied up in court it won't even matter.
