Review of The Fall: Part 1

I'm all for suspending my disbelief to a point but simple facts being conveniently overlooked for the sake of ease of explanation can be annoying! Boyd and Spence went to Dublin to track a suspect, and where treated in Ireland as superior officers and referred to as 'Sir'. At one point Boyd said to the chap he was after that he was a Police Officer - well not in the Republic of Ireland he isn't! Fair enough if this was Northern Ireland Ireland, but Dublin is in the Republic of Ireland and is totally independent from Britain! Boyd and Spence would have had absolutely no jurisdiction there the same way they wouldn't have in France or Spain! Was this laziness on the part of the writer as it was easier to gloss over it, or, worse still, ignorance on the part of the writer? Otherwise - excellent as usual!
