That was interesting about the FBI stats. I didn't know they counted justifiable homicides.All homicides are investigated. But not all homicides are crimes(justifiable, excusable, accidental). Police can't just take your word, that everything you say is the truth. Like police, criminals also lie. Hence why, an incident report with all relevant details and evidence must be filed. The cops may decide not to arrest you at the scene. But, the DA can certainly decide to issue an arrest warrant later.
Let's just define what is reported, and in what category.
"The definition of Homicide excludes the following situations: deaths caused by negligence, suicide, or accident; justifiable homicides; and attempts to murder or assaults to murder, which are counted as Aggravated Assaults.".
"Justifiable homicide—Certain willful killings must be reported as justifiable or excusable. In the UCR Program, justifiable homicide is defined as and limited to:
The killing of a felon by a peace officer in the line of duty.
The killing of a felon, during the commission of a felony, by a private citizen.
Because these killings are determined through law enforcement investigation to be justifiable, they are tabulated separately from murder and nonnegligent manslaughter.
More information about justifiable homicide is furnished in the Expanded Homicide Data section and in Expanded Homicide Data Table 14, “Justifiable Homicide by Weapon, Law Enforcement, 2015–2019,” and Expanded Homicide Data Table 15, “Justifiable Homicide by Weapon, Private Citizen, 2015–2019.”.
As you can see, the incidents you mentioned, ARE reported and tabulated. Under "supplementary homicides", if a homicide is the result. Or, under "aggravated assault", if a homicide is NOT the result. So, unless you can provide some other evidence, homicides(justifiable or not), will NOT be categorized as a burglary, or an attempted robbery.
Read the category about using a gun to threaten someone("scare them off"). So yes, these stats ARE tabulated. That is, if the agencies choose to report them. Since all crime reporting by LEA's is completely voluntary.
I couldn't find the part about threatening (scaring them off).
I would think that the 1510 justifiable homicides would be fewer than the justifiable woundings of attackers but I don't know if those are counted anywhere. I know they happen, though. It is not uncommon for the criminal to check into a hospital after being wounded, often leading to their arrest. And I would think there would be an awful lot of missed shots/warning shots that drove off attackers. I know that this also happens. And I suspect there are a lot more mere displays of firearms that have discouraged attackers as well.
And then of course there are all of the crimes that simply are not even attempted because of the possibility that the potential victim is armed, but it is impossible to prove a negative.
