Political bias must not be allowed to undermine Cahill allegations

Gerard Howlin (Opinion, October 22) takes no prisoners in his full-frontal broadside on Gerry Adams and Co... However, he proffers predominantly only nominal nuance and appraisal, on what is something of a much, much broader, deeper, and more complex archival mosaic.
It is, of course, civilised and morally apposite to investigate and then offer support to people with allegations of rape and alleged cover-up, etc. No balanced empathetic spirit could deny such attention to a worthy case. However the deeper extrapolations and interpretations when couched in polemic á la Howlin, lose credibility as they are trenchantly biased from the off.
