I remember reading a few years ago that women were being steered away from abortion by giving them a blessed rosary. I’m wondering if there has ever been an attempt to sprinkle holy water, blessed salt, or ‘planting’ blessed items at an abortion clinic. Because of the evil of abortion, this would seem to be a wonderful way to cleanse the area, especially when accompanied by prayer and fasting.

Using rosaries, blessed items, and sacramentals to close down an abortion clinic, those are all good measures, especially when accompanied by prayer and fasting. Adoration of the Most Blessed Sacrament, accompanied by fervent family prayer of the rosary, is the best way to protect innocent life. 

We must remember that the Blessed Mother is the one who changed the hearts of the evil human-sacrificing Aztec culture at Guadalupe.  In the protoevangelium (GN 3:15) and in the Book of Revelation, the Blessed Mother is typified as battling with the devil to protect the child.  It is the Blessed Mother who will crush the head of the ancient serpent, the public enemy number one of the human race.  To attack the human race he goes right to the source:  the unborn child.  With no children, there is no future.
 
There are other strategies that can be employed to end abortion, such as education, crisis-pregnancy centers, and changes in the law.  It is a scandal that the majority of Catholics in the United States continue to vote for pro-abortion politicians.  In other places and at other times, the canonical penalties of interdict, suspension, and excommunication were employed with marvelous effect to change attitudes and behavior of the faithful. One wonders if it might not come to that again?
 
In the end, abortion has no future -- just as death has no future -- and it can not continue, or the human race will collapse.  The generations that have failed to protect the unborn over the past 40 years, will be rejected as the enemy of the young in the coming 40 years.  The younger, depleted generation will be unable to carry the burden of caring for the older, feeble generation, and euthanasia of the elderly will be as common as abortion of the unborn is today.  You reap what you sow.
