It needs to be recognized that most lives have a general order to it, in the sense that we have daily obligations that we must attend to, and when this is disrupted in a way and manner in which we cannot attend to those necessary things, it can be debilitating to the person so suffering from that fate, which is why when we look at people that are arrested, and ultimately have their charges dismissed or reduced to something very minor such as in many a misdemeanor, what is not recognized often enough, is that act of an arrest, typically creates a very negative cascading effect upon their life, because whenever those that have obligations to take care of, fail in doing that very thing, this may easily lead to a loss of their job, and an inability to pay for certain bills, and so on, because they have had to devote resources to obtaining bail, legal counsel, and finding a way to replace that loss income.
Look, the law as applied is structured unfairly, so that those that are perceived as being annoying, or don't look the part, or live in a trouble neighborhood, or are in the wrong place at the wrong time, are going to be treated differently than those that live in the most upstanding neighborhoods in which the police in those very nice neighborhoods are typically going to be quite civil and reasonable when dealing with those that live and hence belong in that neighborhood, so that the end result of whether someone gets arrested or is let go, or even treated with the utmost politeness depends upon the perception of that officer, in which the default appears to be, to be harsh upon those that don't look the part, and quite accommodating with those that do. The reason that this is the case is that police officers answer to the hand that feeds them, which signifies that messing with those that have money, status, or power or access to such is considered to be bad form, whereas messing with those that lack those attributes is considered to be "good" policing.
While the law as applied is never going to be completely fair or consistent, seemingly, the least that we ought to see happen is for far fewer arrests to occur on minor incidents, replaced with something akin to a citation, a general summons, a warning, or passing on the issue to social services to attend to, as opposed to an arrest. Indeed, not every interaction that the police have responded to should be escalated to an arrest, and if so, arrests should be segregated into those charges that are serious, as contrasted to those charges which are minor, in which the minor charges are taken to some sort of specialized police station in which the arrestee is "fast tracked" into being recognized, processed, and released in short order, so that they have a reasonable chance to get back on schedule to the things that they need to address on a daily level.
In other words, the very least that the law enforcement apparatus needs to do is to speed up the process, so that people who are being accused of some trivial offense can be quickly excused to be about their business, for unless this nation desires to change its mindset from "innocent until proven guilty" to something akin to a presumption of guilt for all those arrested, which seems to be the way that things currently are, it's going to continue to result in far too many arrests being ruinous to a given person's life.
