Well, I got tired of hearing people say, "The presumption of innocence doesn't apply to bail" -- especially since I got the bail insurance people to stop saying it a couple of years ago -- so I wrote up a short explanation for anyone interested.
You can find it here.
I've been teaching on this a long time with a shorter document that I passed out, but this version incorporates another, more detailed argument that I heard from a very smart prosecutor.
Happy reading (it's not long)!
