remember the red headed gestapo? "This isn't a game, maam."
They were so serious and dedicated, that if they were supporting a noble cause, it would be a source of pride. to us all. But it was bone chilling to realize their serious dedication was to implementing an edict to murder Terri according the proper rules set out by the judge, et al.
If the judge said she was to be murdered, by golly, it will be done right, and by the book!
Same looks of sincerity, same pride in a job properly done, as if their efforts were noble.
