Of course Law has much pull within the NCCB, and I suspect that Law and Mahoney urged Egan to reign in Fr. Pavone. These guys have no guts for real effective pro-life activism.
(That is a generous assessment. When I'm in a foul mood, I'd say its even worse than a lack of backbone, and borders on a complete inability to address mortal sin by the episcopacy due to rampant homosexual sin within its ranks. The evidence is there, see Roman Catholic Faithful's website. Of course, if it is happening, politicos with access to FBI raw files can use such data to blackmail bishops into silence and undercut the effective ministry of the likes of Fr Pavone. This is hard to hear, but the facts are there regarding the homosexual corruption of the episcopacy.)
This billboard campaign is exactly what we should be doing. The analogy with the civil rights campaign in the '60s is quite apt.
The only other pro-life activity that seems to be working to cut the abortion rate is the use of free ultrasound examinations at "crisis pregnancy centers." (FYI, CPC's should be referred to as pregnancy resource centers since there is nothing "critical" about a normal pregnancy).
