Thornton was arrested in March for violating a city ordinance passed last year that prohibits the sharing of prepared food in public parks.In court documents filed Wednesday, the lawsuit alleges the ban prohibits giving food to the homeless in a park but allows anyone to have a birthday party and feed dozens of people.Thornton's lawyers want a federal judge to strike down Bullhead's law and force the city to pay their client $1 for every instance where her constitutional rights were violated.According to the city, Thornton broke the law because she was serving food at Bullhead City Community Park, a public park.In August, Thornton moved her food-for-the-homeless operation to an alley behind a local jet ski store — with the owner's blessing — because of the city's law."
