A controversial gun bill has made its way to the governor's desk.
House Bill 2339 would allow guns in public government buildings like libraries or city buildings unless they have metal detectors and operators for those detectors.
The bill is sparking a big debate.
Deborah Parker is against the bill. She has fought for tougher gun laws since losing her daughter Lindsay Key to a drive-by shooting in Chandler seven years ago.
Key was out celebrating at a Christmas party when she and five other people were gunned down. She was the only one who died, leaving behind a nine month old daughter.
Police said Key was an innocent bystander-- but the shooting was gang-related.
"The person who killed her was a felon and he had an AR15," Parker said.
Parker, a gun owner herself, worries this bill would put more people's lives in danger.
"I have no way of knowing if you're a bad guy with a gun or a good guy with a gun. No way for me to know until you start shooting and it's too late," Parker said.
That's why she teamed up with a group called Everytown for Gun Safety . Several mothers and children who have personally been affected by gun violence made the trip to the governor's office Monday, dropping off cookies and letters.
They urged her to veto the bill.
"I want families to enjoy life, not be threatened by big guns in pockets or on shoulders," Parker said.
Right now under Arizona law, gun owners have to store their guns in lockers if they see a sign on a public building prohibiting firearms.
But supporters of the bill said it's about protecting their second amendment rights.
"If they're going to disarm you and deprive you of your right, they have some obligation or reasonable assurance you're going to be safe. A sign's certainly not a safety measure," said John Wentling with Arizona Citizens Defense League.
Wentling pointed out that only concealed carry permit holders who have already been through background checks and training would be allowed to carry their guns inside public buildings.
"How do they know there's not guns now? Are they reasonably assured that there's not guns now?" he said.
