The proper response to her family is: Sorry, but we’re going to prosecute them anyway. It’s not just about YOU and what the deceased might have wanted. It’s also about protecting the rest of society from these thugs.
Of course, this is the SF area, so who knows what will happen.
The flip side is true as well. When, long ago, my sister was murdered, I had a discussion with my pastor. Told him I would have no compunction whatever about standing the man up against a wall and blowing his brains out myself (and I meant it.)
He said, "That's why we have a justice system."
The weeds of liberalism bear bitter fruit!
