It certainly shouldn't surprise anyone that an abortionist, a person who regularly commits the most gruesome barbarities on preborn children, would feel no moral constraints whatsoever about directing his violence towards others. And indeed, this has happened often. Abortionists have been caught abusing their spouses (even murdering them), violating their patients and co-workers, and frequently venting their rage on peaceful pro-lifers.
This story, a case where an abortionist was perhaps motivated by fears of having his illegal activities caught on film, is just the latest example.
