There were lots of bootleggers behind bars when prohibition
was repealed.

They stayed there.

Now for a case that hadn't reached a verdict yet, you might
get a jury nullification, but don't count on it.

the proscribed items to vanish, it just stopped the
production of new ones, and drove up prices of old ones.
