  • Spike in shootings started when the Laquan McDonald video was released

  • Tickets for Hamilton‘s Chicago run will be superexpensive

Individual tickets for the Chicago production of the hit Broadway musical Hamilton aren’t on sale yet, but they won’t be cheap. In New York tickets, which range from $67 to $477 at face value, go for as much as $2,000 apiece on the secondary market. According to the New York Times, when producer Jeffrey Sellers saw the initial proposed ticket prices for Chicago, he told staff to raise them, because Chicagoans are “just as rich as the folks in New York.” [New York Times
