Ars was able to find the same document on a Danish website by searching on Google for filetype:ppt „operation pacifier“ (we have republished it here). When changing the filetype to PDF, we also found a related document on a Colombian government website and republished it as well.
The Danish document is an undated presentation by Rob Wainwright, director of Europol, who notes that more than 3,000 criminal cases (34 in Denmark) have been generated by the European Union-wide law enforcement agency. The Colombian document simply makes reference to the operation in a summary of „trans-national operations,“ and it includes others called „Operation Moulin Rouge“ and „Operation Red Eclipse.“ It is not clear if those initiatives are related to this child-porn sting.
