> In SF, when the DA refuses to prosecute a criminal and that criminal goes on to kill another person, did that DA fail to protect that victim from future harm?
Yes, of course is the answer to your question. Chesa Boudin is guilty of causing harm to a large number of people for failing to secure the livelihood of people living in SF!
That's the major reason why I left last year, I couldn't take the level of crime and apathy from police regarding criminals. Am I going to let the city's governance play Russian roulette with my life? No thanks, I'm a free citizen in a liberal democracy so I can take my life elsewhere.
