Maybe because it's Christmas Eve Day so nobody at the SFPD is getting back to us. But we'll just put this out there and perhaps you, dear readers, can confirm? A tipster tells us that a "portapotty [was] set ablaze at washington btwn polk and larkin" last night. True? We hope not. Or maybe kind of. Really, this story tickles us. Because we're five. Anyway, this would make the 13th portable toilet to get torched since November.
