Because some of the people Danny works with do not need to see

Oh you know...girls who go into alleys at night with men with bad fashion sense, a dental hygiene issue and that they've just met, Lindsay (Danny's ex sorta in the I don't they were dating so much as sleeping together and she was MEAN to him), Osama Bin Laden, people who murder people while I'm trying to be out on a date or have sex (please have the decency to murder someone during normal business hours, thanx), the grabby man on the subway the other day (broken fingers FTW)

You know...stupid people.
