Taking negligent actions that lead to the death of another person is often a crime of manslaugter. Manslaughter usually doesn't require any other crime to be committed. Therefore, "no laws were broken" ... "leading up to the death of Tayor" isn't relevant to at least some of the relevant charges.
In Kentucky, KRS 507.040 defines "Manslaughter in the second degree" (https://apps.legislature.ky.gov/law/statutes/statute.aspx?id...).
This is defined as:
> A person is guilty of manslaughter in the second degree when he wantonly causes the death of another person...
A "wanton" state of mind in KY is defined in KRS 501.020 (https://apps.legislature.ky.gov/law/statutes/statute.aspx?id...
> A person acts wantonly with respect to a result or to a circumstance
described by a statute defining an offense when he is aware of and consciously disregards a substantial and unjustifiable risk that the result will occur or that the circumstance exists. The risk must be of such nature and degree that disregard thereof constitutes a gross deviation from the standard of conduct that a reasonable person would observe in the situation. A person who creates such a risk but is unaware thereof solely by reason of voluntary intoxication also acts wantonly with respect thereto.
Now, this quickly gets fact specific, but if the following acts are true:
- LMPD breached the house suddenly, and loudly
- LMPD breached the house late at night
- LMPD officers were wearing plain-clothes
- LMPD officers did not announce themselves (disputed)
I personally would find that the officers acted wantonly in a manner that would predictably created a serious risk of injury or death to themselves or bystanders. As such, given the statute and those 4 facts I would be willing to vote to convince on second-degree manslaughter in this case.
I'll note, again, that this is fact specific. The officers specifically claim to have loudly announced themselves. Walker and neighbors dispute that fact.
