Every Duel you missed

A 24-year-old man has deliberately set five small fires in vacant lots over the past year, each preceded by mounting tension and followed by pleasure and relief while he watches the firefighters work, and he collects fire-department scanners and memorabilia. He denies seeking money, revenge, or serious damage; his history shows no fights, theft, lying, truancy, running away, or other rule violations, and there were no mood episodes, psychotic symptoms, or intoxication during the acts, although his arrests have cost him his job.
