How many people are arrested a year for defecation?

how many people are arrested a year for defecation, i have been hearing more and more bizarre reports and news stories about crazy stuff like, these sick fecal tales are becoming more and more common, someone even put feces in my bag when i was at the pool, so i was wondering if as a nation we are increasing our population of deranged fecal creeps (note i live in american for any of you that thought i was refering to australia or the uk)
