I'm not sure how many cases you've prosecuted, but I've prosecuted a bunch. I can't see any way ACORN - in any manner - comes into this "case", whatever this case is. Furthermore, if you think that discovery will yield a trove of treasure with respect to either ACORN or information about Mary Landriue's goings-on, you have absolutely no idea how discovery works.
Depends on the jury.. if there IS one..... ha ha.
What if O'Keefe has evidence of wrongdoing between ACORN and Landrieu? After all, ACORN is based in New Orleans.
