Why didn't the Jedi investigate Anakin's conception?

He was a pretty big deal and had a miraculous conception of sorts as far as the Jedi knew. Seems worthy of investigation.

What's to investigate? His father was the force. They knew it could happen, they knew how it can happen, and they knew it would happen. Using the force, Qui Gon knew that Shmi wasn't lying, and using the same techniques, the Jedi council knew Qui Gon wasn't telling porkies. 

Perhaps the only question remaining is: "why Shmi?" ... but this line of reasoning is anti Jedi thought. A well conditioned Jedi focuses on the moment at hand, and the moments to come. The past is unchangeable, so there is no point in dwelling on it. Residing on things past can only lead to malcontent... which will lead to the dark side.

I think the only way the Jedi would investigate this further, is if immaculate force babies started popping up everywhere. This would be unexpected, and have a large impact on the future AND the present.

As it stood, there was one force baby, he was expected, and he was under close observation by the Jedi council. Things done be covered.
