Ohio Gov. John Kasich has signed bills into law that shield the names of companies providing lethal injection drugs, regulate traffic cameras and allow hunters to use noise suppressors under certain conditions. The governor also signed bills that put in place sweeping changes to municipal tax collection, regulate teen use of tanning beds and create a three-day back-to-school sales tax holiday next August. The bills were among 40 signed Friday by Kasich following the Legislature's lame-duck session.
