An excellent article found for us by TDI instructor Gary Hoff on the issues of self defense examined in the investigation of the Charlotte police office in the death of a suspect.
For our Ohio students, note the recognition that in Ohio, unlike other states, the burden of proving self defense lies with the defendant (or potential defendant). That means in a self defense situation you have the burden of proving all of the elements of self defense. Fail to meet that burden and conviction is likely.
This nuance of Ohio law is taught in our Ohio CHL portion of Handgun 1-2 by our instructor who is also a practicing attorney.
