Kansas has a law on the books that allows the People to call for a grand jury if the state's prosecutors won't. It has rarely been used, though it has been used twice to bring grand juries together in the interest of charging Dr. George Tiller - a doctor who performs late-term abortions. The allegation is that Dr. Tiller performs abortions in violation of the narrow scope authorized by Kansas law.
Last year, there was a Supreme Court case, Bell Atlantic Corp. v. Twombly, which turned out to create a very difficult burden for Class Action attorneys. In the past, one could allege an injury and then show the harm through discovery. Now, you have to be able to show some harm from the allegations in order to even bring the case to trial - this is a very difficult burden for Plaintiff's Lawyers, who often do not have access to the records and files needed to show the harm except through discovery, and with Whistleblower protection going out the window, the country has become very Big Business friendly in the matter of a very, very short time. But I digress. This type of protection could be useful in grand jury matters such as we see in Kansas with Dr. Tiller. The Doctor has a vested interest in protecting his patient's privacy, but the pro-life crowd seems to think those people are immaterial in their hunt for blood (perhaps literally, Dr. Tiller was once shot in both arms).
At any rate, the Judge in the case did grant the motion to quash until the court considers the issue. Small victories.
I don't quite get the visceral hatred that pro-life organizations get into with this issue (particularly when I have heard eyewitness accounts of picketers going into the clinic to get their own abortions only to return to the picket line afterwards). Rather than attack the individual, attack the law. Support an amendment overruling it. Don't go on fishing expeditions to headhunt and bully people into supporting your cause - that just hurts in the long run.
