Family Limited Partnership - Asset Protection?

I went to an Apartment Association Convention and they had many speakers. One was an attorney who said that if you own property you are a target. He want on to say that an LLC is piercable, and that the best line of defense was to form a Family Limited Partnership. He said that was bullet-proof. He said it was similar to a pension plan that no one can touch - remember the OJ case. That pension was untouchable. So now I am thinking that I should form an Family Limited Partnership instead of an LLC. Has anyone heard about this?
