(Photo by Wade Payne/Invision/AP) (Newser) – A Keith Urban concert near Boston last night resulted in a lot more reckless behavior than police expected. Some 46 people received medical treatment and 22 were hospitalized, mostly for alcohol-related illnesses, Reuters reports. "Last evening's Keith Urban concert was not anticipated to present with the volume of issues handled, but measures were in place to provide appropriate and adequate care and protection to all patrons," police said, per the Boston Herald. Police took some 50 people into protective custody. Was Urban aware of the trouble? Well, he later tweeted that things had been "nutso" on the lawn at the Xfinity Center, the Herald notes.
