No Code of Conduct
The Phoenix Trotting Park made its big-screen debut in the 1998 film "No Code of Conduct" starring Charlie Sheen and Martin Sheen. The building can be seen prominently in several shots and was used for a major explosion scene towards the end of the movie. The explosion became a source of controversy for the movie's production crew after a number of pigeons were killed or injured during the blast. 
"No Code of Conduct" is an action movie starring Charlie Sheen and Mark Dacascos. It was written and produced by Bret Michaels (of 1980s glam-rock band "Poison" fame). The movie was produced by Dimension Films and Toddler Pictures and released in December 1998. Budget for the 95-minute film was $12,000,000. 
The film centers around police officers Jake Peterson (Charlie Sheen) and Bill Peterson (Martin Sheen) as father and son detectives who uncover a conspiracy to smuggle drugs from Mexico to Phoenix. It is a high-action film with a car chase, shootouts, and avenging the death of a fellow detective.
The film ends with a dramatic showdown between the good guys and the bad guys that results in a massive explosion at the Trotting Park. At the time, the abandoned grandstand had been inhabited by a large number of pigeons. When the explosion scene was filmed, many of the birds were killed or received burns from the heat and flames. An anonymous tipster called two local organizations, Wildlife Concepts and Urban Wildlife Society, who rescued and provided aid to nearly all of the injured birds.
The directors and production crew were criticized for not doing enough to prevent injury to the pigeons inhabiting the Trotting Park. Although they were not a protected species, the unintentional injuries to the birds prevented the film from being approved by the American Humane Association, which publishes guidelines and advisories for animal use in films.
