The courts created this mess because they imposed abortion on the American people instead of kicking the issue back to the legislative bodies where it should have been resolved. The legislative process is messy and doesn't guarantee the left the outcome they want.
Now we see a killer (we presume killed because the guy was an abortionist) and get a little excited because the abortionist got a little "street justice".
IOW, the issue is only heating up because of the courts not inspite of them.
Since I believe everything is by the hand of God, it is more appropriate to ask if the death of Tiller is by the direct action of God. In the same way as God saw to the death of Herod Agrippa I, this, too, could be by the direct appointment of God. After all, Tiller was a serial murderer.
