Bear with me, being a relative newcomer, but would this necessarily set such a precedent? 

 To many here in the UK who actually remember the news coverage at the time, the omission of Dr Sheila Cassidy might seem a little odd. Although the names of other foreign nationals that were incarcerated by the DINA are omitted directly from this English version of the article (my foreign language choices at school did not include Spanish, so I can't check that page directly), they are mentioned with reference to Operation Condor. 

 I see no problem in mentioning that Cassidy and some other notable foreign nationals were incarcerated by the DINA under Pinochet's rule. That this happened is a fact, after all, and not in dispute. The level of detail devoted to this would, I agree, lead to some interesting editorial speculation here in the talk page, but the addition of the basic facts I see no problem with. 

 Such a statement would, after all, be restricted entirely to persons incarcerated by the DINA, which should narrow the field somewhat with regards to extraneous additions???
