Wisconsin Capitol Police Chief Charles Tubbs, who telephoned Meade today, suspects that the police put the handcuffs on the door in an effort to keep protesters from breaking into the Capitol on the night of March 9th.
As I noted in a post on March 11th, Meade had the impression that the protesters had put the handcuffs on the door, but he was "trying to get an authoritative interview from the police." He left a message with Tubbs, and Tubbs called back to say that he was investigating and would call back, which he did today.
Putting handcuffs on the door is obviously a hazard, especially once people got in through other means. (Meade observed a window opened to the office of Assemblyman Cory Mason that night.)
I look forward to more investigation into what happened that night, when the police were overwhelmed and, apparently, resorted to handcuffing the doors shut. I have heard from some police officers who feel demoralized about the way they have been disabled from keeping order.
