The Indiana House has approved a controversial measure that would allow guns in parking lots of Hoosier schools as long as they're inside a locked vehicle and out of sight. It's a provision that was added to Senate Bill 229, legislation that also would ban taxpayer dollars from being used for gun buy-backs. The House vote was 74-24 in favor. The measure now goes back to the Senate. Opponents are concerned access to guns so near to schools could lead to school shootings. Supporters say the bill would protect parents from accidentally committing a felony if they have their guns with them when they pick up their kids from school. It would remain a felony to bring a gun into a school building.
