Anybody have an example voir dire on a delivery case using confidential informant. Curious as to ways to educate jury on CI issues

If you want to know what the biggest baddest gang in town is up to, who do you have to talk to? Cops aren't gonna' know. People on the street aren't gonna' know. You have to talk to people inside. A bit sillier but still appropriate example is if you want to know what's happening inside the snake den, you gotta' talk to some snakes. There's no other way to do it.

Thanks. Also heard "if you want to try the devil you need to go to hell to get the witnesses"

I appreciate the suggestions
