Nope. Not justifiable. The man that pushed him down didn't have a weapon. He wasn't even continuing to assault him. For stand your ground you have to feel not just a threat, but a threat for your life. Being pushed to the ground is in no way a threat on your life.

Has no bearing on the case now.
Sure it does. If it goes to hearing. Defense will produce incidents and professional testimony of death due to head injuries from being pushed or falling onto hard surfaces. That reasonable fear is justification for lethal force under Florida law
A jury will never see such evidence or hear such testimony. Michael Drejka (hereinafter referred to as the defendant), did not kill Markeis McGlockton (hereinafter referred to as the victim) because he feared being shoved. He shot and killed the victim after he had been pushed to the ground. The potential injuries from that shove are as meaningless as the price of wheat in China and the actual injuries the defendant received are equally irrelevant. You are not familiar with Florida law so I will explain. First, here are the applicable Florida Statutes which define when and what type of force can be used in self defense:
776.012 Use or threatened use of force in defense of person.—
(1) A person is justified in using or threatening to use force, except deadly force, against another when and to the extent that the person reasonably believes that such conduct is necessary to defend himself or herself or another against the other’s imminent use of unlawful force. A person who uses or threatens to use force in accordance with this subsection does not have a duty to retreat before using or threatening to use such force.
(2) A person is justified in using or threatening to use deadly force if he or she reasonably believes that using or threatening to use such force is necessary to prevent imminent death or great bodily harm to himself or herself or another or to prevent the imminent commission of a forcible felony. A person who uses or threatens to use deadly force in accordance with this subsection does not have a duty to retreat and has the right to stand his or her ground if the person using or threatening to use the deadly force is not engaged in a criminal activity and is in a place where he or she has a right to be.
History.—s. 13, ch. 74-383; s. 1188, ch. 97-102; s. 2, ch. 2005-27; s. 3, ch. 2014-195.
In interpreting law, a basis tenet is that each word is significant. In the quoted statute deadly force is allowed when the one using such force “reasonably believes that using or threatening to use such force is necessary to
PREVENT imminent death or great bodily harm to himself or herself or another [innocent third party]” (explanatory insert and highlights are my own). The key word is PREVENT. The use of deadly force is allowed to prevent death or serious bodily injury not to seek vengeance for a harmful act already committed. If a man knocks you to the ground and you shoot him while he is running away you are begging for some serious prison time. You seem to think that somehow the defendant was protecting himself from sort of harm by killing the victim. One word: Ridiculous. Whatever injury the defendant sustained as a result of the shoving would be not have been avoided nor alleviated by killing the assailant afterwards..
The actual shoving incident does not give rise to a legitimate a claim of self defense. The defendant should be charged and convicted unless there is something more to the case than already known. For example, if after having shoved the defendant to the ground the victim had threatened to kill him, the psychical contact may have convinced the defendant the man's threats were serious and deadly force was necessary. However, I am convinced that the shoving incident stands alone and there were no other threats. The conduct displayed by the victim in the video is completely inconsistent with a man who threatened to continue a violent attack. Additionally, if such threats were made they would certainly have been included in the police report.
There is only one question that must be asked to determine whether the defendant's conduct was self defense and therefore lawful or a criminal violation of the law for which he should be prosecuted: At the precise moment the defendant pulled the trigger did he reasonably believe that deadly force was necessary to prevent death or serious bodily injury to himself? If the answer is yes, he acted lawfully in self defense; if the answer is no, he must be charged with the unlawful taking of a human life.
CONCLUSION: I believe the man will ultimately be charged. All the evidence points to the fact that at the very moment he pulled the trigger, the defendant was not in danger of imminent serious bodily injury or death; therefore the use of deadly force was unlawful.
But that is just my own humble opinion (and yes I lied about the humble part).
