Local police officials have told the Miami Herald that a gun buy-back program has taken 128 guns off the streets, including two assault weapons turned in by a father who lives near Marjory Stoneman Douglas High School, where 17 people were killed by a gunman last month.
The father, also an attorney, Steve Hemmert says in a Facebook post shared nearly 90,000 times that he has "eliminated the hypocrisy of these guns" from his house and can now "feel comfortable" calling on the government to ban them.
Hemmert says his 14-year-old daughter helped him build one of the military-style assault rifles from scratch.
After the Florida shooting, she told her father that she plans to wear only sneakers to school, in case she has to run.
"It may not get all of these guns out of the public's hands. But it will make it a hell of a lot harder for a deranged 19 year old to get his hands on one," the Facebook post says. "I want to be part of the solution.#neveragain"
