LANSING, MI (WTVB) - A bill was introduced yesterday in the state Senate that, if passed, would allow public school districts to allocate monies in their sinking funds to beef up building security, an idea devised in response to the Sandy Hill Elementary School shooting that left 20 students dead. Senator Howard Walker, a Republican from Traverse City, is sponsoring the bill; his Chief of Staff, Eric Dean, told the MIRS News Agency that the idea came from a suggestion by superintendent in Walker's district. Currently, revenue in sinking funds can only be used for building projects, like the ongoing renovation at Legg Middle School in Coldwater.
