Drejka then pulled out a gun and shoots McGlockton in the chest. McGlockton ran back into the store, clutching his chest. He later died from his injuries.
"I could have been killed. My kids could have been killed," Jacobs told WFTS.
McGlockton’s five-year-old son witnessed the shooting.
"I need justice, and this is not right at all," said Jacobs. "How is this 'stand your ground' law? It's not. It's not, and I need help."
The Pinellas County Sheriff's Office said they won't file charges against Drejka under Florida's "stand your ground" law.
"He had to shoot to defend himself. Those are the facts and that is the law," said Sheriff Bob Gualtieri. "No matter how you slice it or dice it, that was a violent push to the ground."
In 2013, the controversial law became the subject of national debate when George Zimmerman shot and killed Trayvon Martin, an unarmed black teenager, in Sanford. Zimmerman was later tried and acquitted.

Drejka is a legal concealed weapons permit holder and will not be charged because of Florida's Stand Your Ground law, according to the Pinellas County Sheriff's Office.
The store owner tells WFTS that Drejka has a history of assaulting people in the very parking lot where the shooting took place.
WFTS knocked on the door at Drejka's clearwater home over the weekend, but a sign posted outside said "no comment."
