People accessing the internet at work? Horrors!
In case I wasn't clear, these edits were the work of individual NYPD employees fooling around on their work computers, not an organized Department-wide propaganda program.
There were 85 NYPD IP addresses linked to Wikipedia edits. As the article notes, only a relatively small number of edits about police incidents were made. So realistically we're talking about how many cops making these re-writes? 2-3? Maybe half a dozen? We're almost surely at least within single digits.
That's out of a total force of 50,000, who are now apparently all "scum". Nothing like painting an entire community for the misdeeds of a view. Odd that the same posters who so assiduously argue that point in other contexts see no problem ignoring the precept when it comes to cops.
You're very generous to point out that it only takes a few people to make the 'correct' changes on wikipedia.
