The only hope people have ever had at truly lowering crime is improving society and investing in the people that live in it. Even the pentagon understands this with rivals in war, or terrorists. The idea that you can tough on crime your way out of this is incredibly naive. As people have already pointed out, the US already incarcerates more than pretty much anywhere else in the developed world. They are objectively not soft on crime. Most people in Europe or Canada would view extradition to the US as barbaric.
Police can't really protect you very often. They try, but at most they will be called to react and it will unfortunately be after the fact most times. They'll pick up the pieces, and maybe if you're very lucky they'll find some evidence to track down the person that did it way later. If you've ever lived in a large city and just seen the amount of streets and the mass amounts of people that live there, the idea that police can truly watch all of that is insane. Maybe if you live in a complete police state like parts of China with AI and facial recognition everywhere, armed check points and zero freedom, zero second amendment, you might get close to clamping down on crime by force.
Unfortunately, the best chance people have of improving things is improving the people themselves and it takes a long time. Investing in good schools everywhere, including and especially in poor areas. Improving pay for teachers. Investing in health care and mental health care for everyone. Investing in affordable housing. These are literally just the basics that keep you off of the street, not some extreme luxuries. But giant chunks of the population do not have access to any of this, and it will get worse in the future. Seems all people can think of is the seductive call of the police state, which won't work anyway.
People focusing on race, and "patterns" in this case are likely racists. You have to actually think that genetically they are just somehow inferior for that to be the thing you focus on. If you don't think they're genetically inferior, then all it means is that there are areas in the US that need more attention, more investment, and more opportunity. They're fellow Americans and either your plan is to lock all black people up, racially profile them and treat them like second class citizens, or you have to actually improve those areas. The less we fixate on race, the less they are isolated and treated differently, the more the outcomes are homogenized. The more opportunity that people have for quality education, health care, and job opportunities, the less likely they are to be a failed member of society.
The police are not nearly enough to be the bandaid for a failed state. The alternative to crime is investment in housing, education, healthcare and improving the lives of people.
Cashless bail isn't the problem. The whole point of being arrested is to determine if you're guilty or an immediate threat. If you're a threat, the amount of money you have shouldn't matter. This guy had enough of a criminal record to be considered a threat regardless of what was in his bank account. The judge and prosecutors failed there. Critics of cash bail are just pointing out that it's irrelevant how much money someone has. That has nothing to do with justice. People have to do a reliable threat assessment, and then protect society. Part of the issue is that there are so many people locked up and processed that the wait can be long, and keeping people in jail for long periods of time before they are charged / particularly if they are innocent, can ruin their lives, get them fired, etc. If we invested in society, had less crowded prisons, people could be kept when needed without a months long delay for a trial.
Society is failing at multiple points, and almost all of it comes down to unprecedented income inequality, and declining quality of life. The rich want that police state because it really is the only card left to play other than investing in people, which they will never do.
