Well it does really. Loads of articles on how annoyed Kate looked, from her horse drawn carriage. Loads of comparisons made between her families lifestyle and normal families in the UK.
Loads of discussion happening on the fairness of it all, and the cover ups being made by the Royal Family.....tax affairs, wills hidden, etc, never mind the disgrace that is pompous Andrew and his scum filled life.
So yes, id say shouting out from a crowd has achieved a lot in this context.
