As a former prosecutor I guess I should say something. Prosecutors have prosecutorial discretion to prosecute whatever they want but will generally defer to what the victim wants (especially on misdemeanors) unless there is some evidence or feeling that the victim isn’t cooperating for untoward reasons (think battered wives, etc). Padres Bro could definitely still be charged and still might, but it would only be a misdemeanor assault charge and the municipal prosecutors probably have their hands full with other stuff.
