You must read this story of Pastor Walter Hoye.  He went to jail (choosing to reject a plea agreement) because he stood outside an abortion clinic quiety and peacefully telling women that Jesus loved them.  Despite video evidence that in no way did he harass any of the women or the workers, he was still convicted by the jury.

But while in prison, he was able to share the Gospel with so many of the men in jail.  Just one more example of how the Lord can use evil for His good purposes!
