I think I've related the old joke about why scientists doing behavioral experiments with animals are considering switching from rats to lawyers: There are some things a rat won't do.
The joke came to mind when I saw this article. Readers may judge for themselves whether a rat would do it.
Sure, defense counsel in a capital case has to push the envelope. It might be proper to seek information about whether the officer charged with inserting the needle has hand tremors or bad eyesight. But the inquiry here mocks -- how shall I put this? -- the evolving standards of decency that mark the progress of a maturing society. Well, maybe not so much. It mocks any decency at all.
We have also seen recent efforts by the bar to ban comfort dogs used to help terrified child rape victims when they testify, and to pooh-pooh the sexual sadism that went on in the Petit murders by saying (almost certainly falsely) that Mr. Nicey didn't really sodomize the 11 year-old victim before he burned her to death, he "claimed only to have 'ejaculated upon' the girl,"
This kind of stuff is what some call "acting in the highest traditions of the profession."
