Nope, cops are trained to shoot that way. It's intended to stop a threat, not kill.
The fact he shot him multiple times will not be a factor nor does it make this premeditated in any manner.
What it comes down to is the deputy overreacted to the site of the handgun.
I have had several LEO buds defend what he did, but the video clearly shows there wasn't justification to shoot him as having a weapon in your hand does not automatically make a person a threat.
However, let's be clear and the terms and what they actually mean in the State of Florida Penal Code...
Homicide is a blanket term that describes any event in which one person causes another person’s death. Anytime someone is killed by the action of another person, it is deemed a homicide.
Murder is defined as an act of intent, which means that an intentional act was carried out, and someone died as a result. Murder is the intentional and unlawful killing of another person. In the courtroom, establishing a charge of murder requires proof that premeditated planning took place (first-degree murder) or an act in the heat of the moment urged a person to intentionally kill another person (second-degree murder).
Florida law differentiates two types of murder: first-degree murder and second-degree murder.
First-degree murder is premeditated and occurs when the intentional act of killing another person takes place. It is also used to describe murder that occurred in conjunction with certain other felonies, such as kidnapping or robbery. In Florida, first-degree murder is punishable by life in prison and may even elicit the death penalty in some cases.
Second-degree murder is not premeditated or planned out in advance, but it still involves the intentional killing of another person. It occurs when one person causes the death of another person in the heat of the moment but intentionally. This can happen within a fight or argument that just happens to escalate so far that it leads one person to make an intentional decision to kill the other person. It was not premeditated, but it was intentional, nonetheless. Second-degree murder in Florida can get you a sentence of life in prison.
Manslaughter is the unintentional killing of someone else. It involves the unlawful killing of another person without premeditated intentions and/or an intent to kill. If someone means to harm someone else and happens to inadvertently kill them instead, it is manslaughter. A conviction of manslaughter does not require the prosecution to prove that there was an intent to kill or an intentional cause of harm. Instead, it must simply prove that the defendant killed the other person.
Manslaughter is also divided into two categories: voluntary and involuntary.
Voluntary manslaughter occurs when someone unintentionally kills another while they are committing another felony. It can also arise within a fight or argument, like second-degree murder. However, there is no intentional act of killing when manslaughter occurs. There may be an intention to harm but not to kill. Florida voluntary manslaughter charges will garner a maximum of 15 to 30 years in prison for anyone convicted of these charges.
Involuntary manslaughter, on the other hand, involves someone killing another person unintentionally, not while committing another felony, but due to their own negligence, recklessness, or lack of responsible behavior. Involuntary manslaughter can carry a penalty of up to 15 years in prison in Florida.
This was involuntary manslaughter, it doesn't meet the burden of proof for second-degree murder.
