There is so much law against doing something like that, it isn’t funny. You can’t even use peremptory (without reason) challenges to exclude people on basis of race or creed.
I’m with Eleutheria5 on this one, a first year law student knows this won’t fly, hopefully. But today apparently an experienced attorney thinks it might, or perhaps raise an appeal issue. At the very least, not be an embarassment to raise the issue. That’s a shame.
