Six years after the killing of Trayvon Martin put "stand your ground" laws under a microscope, attorney Benjamin Crump is representing another Florida family who lost a loved one under the law.

The case of Michael Drejka, who police say fatally shot Markeis McGlockton last week in Clearwater after McGlockton shoved him for confronting his girlfriend over a handicapped parking space, differs considerably from that of George Zimmerman, the man who killed 17-year-old Trayvon. Despite Trayvon's case highlighting Florida's "stand your ground" laws, Zimmerman ultimately opted to pursue a self-defense case and prevailed.

But Crump sees similarities. Drejka, he told CNN, was "the initial aggressor" and was acting as a "self-appointed cop wannabe" in hounding McGlockton's girlfriend about the parking space. Crump made similar claims in 2012, when information surfaced indicating ZImmerman had described the 17-year-old Trayvon as "suspicious" for walking through the neighborhood where his father lived and defied a 911 dispatcher's instructions not to approach the youth.

Crump believes that "stand your ground" is being applied to the wrong person in the Drejka case. Drejka killed McGlockton after being shoved, and Pinellas County Sheriff Bob Gualtieri said Florida's "stand your ground" law prevented him from arresting and charging Drejka.

"Mr. McGlockton has the right to stand his ground when he comes out and sees his family being verbally assaulted," Crump said.

Gualtieri disagrees and has ardently defended Drejka, describing McGlockton's push as forcible and violent.

"(Drejka) felt after being slammed to the ground that the next thing was that he was going to be further attacked by McGlockton," Gualtieri said, adding that the time between Drejka hitting the ground and the shooting was about four to five seconds.

The only relevant issue in this case, the sheriff said, is whether Drejka was in fear of further bodily harm.

Repeated attempts to reach Drejka have been fruitless. CNN affiliate WFTS reported that the 47-year-old put a sign outside his home that read, "No comment."

'My man is defending me'

Britany Jacobs, 25, says Gualtieri and investigators have it all wrong. She says that McGlockton, her boyfriend of nine years, was defending her and their three children, two of whom, one 3 years old and the other 4 months old, were in the car with her at the time. Five-year-old Markeis Jr. had gone inside a convenience store with his father.

Jacobs concedes she parked in a handicapped spot Thursday outside the Circle A Food Store in Clearwater, and told "Good Morning America" that Drejka pulled up in a silver SUV and began yelling and cursing at her.

"(McGlockton) comes out and sees a guy yelling at me and I'm sitting in the car. So, by this time, my man is defending me and defending his children so he pushes the guy down," she told the ABC show.

Surveillance footage from the store shows McGlockton exit the Circle A and make a beeline for Drejka, who he shoves upon reaching him. Drejka tumbles back onto his butt as McGlockton briefly stands over him, pulling up his shorts.

Drejka pulls out a gun and McGlockton steps back and quickly clutches his chest before running back into the store and collapsing in front of his son. There is no sound on the video, but the Pinellas County Sheriff's Office said in a news release, "Witnesses told detectives that Drejka was on the ground when he took out a handgun and fired one single round at McGlockton striking him in the chest."
