A few comments from a local with some knowledge of the area. I personally don't know the barrister, but she was a fairly prominent person in the anti-repeal movement. So you could guess her disposition with respect to wearing thongs, etc.
I'd also be concerned about the quality of the prosecution. Cork is in the midst of a whole series of sexual assault reports, cases that have been on-going for the past few years. Rape cases from the recent concert tour bus failed in court, series of rapes in a local park, rapes of 1st year students (that's a regular event in Cork).
Some of the people in the Cork march were those working in the city centre area, who would have some insight in the cases, so it encouraging to see them supporting. They KNOW what is going on, the lack of resources, etc.
OP says "By the way, the guy got off." .. How can you be sure? DNA evidence plays an increasingly important role of how jurors respond in court (exposure from various TV shows, high profile cases). At this moment in time, it's a key supporting factor in getting a conviction.
More gardai investigation resources, better and more prompt prosecution services are all badly needed in Cork
