Supporters of the mangana and piales events argue that catching horses by their legs has been and is a legitimate method of animal husbandry and therefore part of a celebration of traditional ranching methods of Mexico. This is evidenced by the veterinary and ranch work exemptions in the California, Arizona, New Mexico and Texas statutes. They also note the inclusion of mangana and piales in Charreada rules promulgated by the FMCH as proof of the tradition of catching horses by their legs.
