NEW: Assault charge DROPPED in viral Washington Square Park snowball fight case. DA Office declined to move forward with an assault charge against 27-year-old Gusmane Coulibaly, instead filing a misdemeanor count of obstructing governmental administration and a harassment violation. According to prosecutors, a review of the evidence did not establish that an officer sustained a physical injury directly tied to Coulibaly’s actions, which is required to support an assault charge.
