BY MATTHEW ALBRIGHT | Staff writer The principal of Walker High School has asked to go on leave for the rest of the school year after he became a lightning rod of criticism at the school and on social media. A student and her mother accused Jason St. Pierre of removing her from her role as student council president and revoking help with a scholarship because of a video that showed her dancing at a private after-party for the homecoming dance. St. Pierre issued an apology Sunday and said he was restoring what he took away, but the anger remained. Here's the latest. Gunfire rang out at a Gonzales park late Sunday night, causing a chaotic scene: Four people were shot, and three more were hit by a car fleeing the shooting, of whom died. Here's what we know about the shooting, including why so many bullets flew. After a meltdown in Baton Rouge's school bus system canceled class and left families in the lurch, some in the city are wondering: Why doesn't the district privatize the service, as others have done? The answer is: it's complicated. But one big factor is a law passed more than a decade ago that sets rules for employee retirements, which would blow a big hole in the district's budget. Here's why it's an obstacle, and why it matters. |
