It’s been 20 years since the shootings at Columbine High School in Colorado. Back then, school shootings were a horrible anomaly; now, even more horribly, they’re commonplace. Innovocative Theater is devoting its entire season to the subject of school violence, beginning with Columbinus, a mix of fact and fiction that addresses “the fatal consequences that result when a culture succeeds in weaponizing the alienation and angst of its own children.” The theater will be holding post-show talk-backs after weekend matinees, with guests including Manuel Oliver, father of a student killed during the Parkland shooting.  Jan. 11-20, Fridays & Saturdays at 8 p.m., Saturdays & Sundays at 3 p.m.,  Innovocative Theatre Company at Stageworks Theatre, 1120 E. Kennedy Blvd., West Building #151, Tampa. Tickets: 813-374-2416 ext. 1, stageworkstheatre.org. More info on the production at innovocativetheatre.org.
