over reaction
Personally, I think there's been an over reaction to Horan's action. I also thought Joe Duffy was the biggest offender on his show today.
It was nutty, it was stupid but for goodness sake people, Horan dressed in a funny costume and pushed someone. Shure that happens every night of the week in cities and towns all over the world. Nobody was hurt, nobody died.
To be fair, I didn't see the whole incident live, only the very brief clip shown on RTE news programmes, so I have no idea how what happened affected the runner involved, how far ahead he was at the time, or by how much he was beaten to the line.
By the way, exactly what law was broken when he ran on to the F1 track or what he did in Athens?
