Some mothers said Friday they disapprove of a controversial state law that goes into effect July 1, making it legal to carry guns in Indianapolis city parks and playgrounds, which is currently banned by a city ordinance.The new law generally prohibits local governments from regulating firearms, 6News' Joanna Massee reported.Mothers who brought their children to Garfield Park told 6News that they disagree with the law."Why would you need a gun at the park? You're supposed to come to the park to play with your children," said Eyvonna Hyatt, who has a 3-year-old daughter and a baby on the way. "Kids get shot every day with guns, because they're playing with guns. What are you going to do when you bring your kid to the park and you've got your back turned and your kid takes your gun?"Tarra Higgs, a mother of three, said she is also opposed to allowing guns in parks and playgrounds."If I was to bring my kid to this park, and I (saw) somebody here with a gun, even if they had a permit and it was on their side, I would still probably leave," Higgs said.The argument in favor of allowing guns in parks and preventing local governments from regulating firearms stems from the Second Amendment.State Rep. Mike Speedy, R-Indianapolis, sponsored the bill in the Indiana House."This law only speaks to those that have permits that are law-abiding citizens," Speedy said, adding that it opens up local governments to litigation if they pass contradicting ordinances."I feel like it's a fundamental freedom to have the right to protect yourself, the right to self-preservation," Speedy said.Under the new law, local governments will still be allowed to regulate the discharge of firearms.
