Yes it does, I watch snapped all the time and every single woman who killed her husband in cold blood who claims it was "self defense" nine times out of ten called the police 1st or immediately after. If you are going to use self defense to cover your butt it's common sense you'd call the police.
Did the women on Snapped kill their husbands outdoors with lots of disinterested potential witnesses within yards of the killing? If not, I don't think the same rationale applies. jmo
