Too bad the resident has to run the gamut of questioning by police, media, and district attorney.
Can't understand what the police would want to investigate. It would seem to be a righteous shooting case.
In OK there is little police questioning after a good shoot, especially where an armed home invader is killed. Unless the police have good reason to believe a law has been broken, the shooter can't be arrested. Most OK prosecutors simply decline to prosecute righteous shooting cases; no grand jury, no nothing. The family of the late perp is not allowed to sue in civil court.
Our former Comanche county prosecutor gave three passes on fatal shoots in one 18 month period.
