Pastor Rodney Francis told FOX2 keeping toy guns away from children may help end our "culture of violence."
"It is all about changing the way they engage with others," Francis said. "I don't know why would people ever think that it is okay to let kids play with things like that."
108 people were shot to death in St. Louis in 2012.
"That is more than a problem," Francis said. "People are getting killed."
There have been 19 murders in St. Louis in 2013.
18 of those people were shot to death.
"This needs to be part of our conversation about ending this violence," Francis said. "It is one aspect of this problem."
During an interview after two officers were shot, St. Louis Chief of Police Sam Dotson said that "society" needs to do something to keep guns away from criminals.
"It all starts when they are children," Francis said.
Francis is still working on the details of the toy gun buy back.
