If the police fail to arrest someone, that is on them. No passing the buck.

Can you cite which DA said that about what crime, other than marijuana possession?

Let's not turn them into powerless victims, act like that is the only response police get, that they are such vulnerable people, or that it is not partly a consequence of their actions. They get all sorts of responses from lots of people, and as public officials, criticism is a part of the job. Arguably, if they did their jobs better, they wouldn't be criticized as much.
But rather than changing the subject, a far more important issue is police abusing civilians: The police have a lot of power, well beyond criticism, which ruins lives. Far more important than protecting the suddenly fragile police officers' self-esteem are justice and freedom.
