Sir, - I wish to complain strongly about the police-horse dung which is becoming a regular feature on Grafton Street. I skidded on a fresh patty last Saturday and, apart from the mortification, I had to throw out a new pair of casual trousers. Who is answerable for this? Do the normal antilitter regulations not apply to police animals? - Yours, etc., Mark Tarbatt,
Rutledge Terrace, South Circular Road, Dublin 8.
