School Board chairpersons around the state today received an email blast from the Pinellas County School Board encouraging boards to support a ban on assault weapons.The simple, two-sentence letter notified boards that the Pinellas board voted 6-1 to officially support the ban at a meeting Tuesday."We also voted to encourage other school boards in Florida and around the country to support such a ban," it read.Linda Lerner motioned for a vote, and all but board member Carol Cook voted in favor. Cook said she did not want to "burn any bridges" with a legislature that did not even want to discuss banning assault weapons, citing other priorities like Gov. Rick Scott's proposal that she'd like to see become a reality.This is a second day the Pinellas County School Board sent a letter urging others to get on board with school safety measures in light of the massacre at Marjory Stoneman Douglas High this month. On Wednesday, the board and school superintendent Mike Grego penned a letter to all Florida legislators urging them to support Scott's $500 million school safety plan.
