If you theory is correct, it would explain why Beelzebubba and Her Satanic Majesty rammed through the Federal Access to Clinic Entrances FACE Act which largely put Operation Rescue out of business but the numbers of abortions per year are still below maximum levels of previous years. The SCOTUS (in a decision by Stephen Breyer!!!) had also ruled that the federal racketeering RICO statute could not be applied to pro-lifers for clinic actions.
Nonetheless, so long as activists of Operation Rescue and of the Pro-Life Action Network and similar groups survive to tell the tale, there will always be an underground resistance to abortion awaiting further opportunities for effective moral action.
I know as a pro-abort show of force in Dallas, in 1989, there were 3 abortion clinic "bombings" that took place which the pro-aborts hoped would knock OR a big whammy. The leaders in OR were questioned about involvement.
A friend of mine was personally questioned by the ATF. After being interviewed, she asked the guy what the deal was and she was told that all the evidence pointed to an inside job in all 3 of the cases.
One clinic had its front desk destroyed which was found out to have had a liquid accelerant sprayed on it that flames up and quickly dies out it didn't to more damage than to just the desk.
Another had all of its patient records destroyed only which indicated that the same accelerant was used and btw - that clinic was at the time involved in a law suit where a woman had died at the clinic.
And the last clinic had its outside air conditioning unit destroyed.
The ATF guy admitted that they always know when pro-lifers are involved because they go straight for the suction equipment.
Curiously, the media never did present an update concerning the inside job opinion of the ATF and let people continue to think that Operation Rescue was the culprit.
