People are arrested all of the time for various things, in which, at the very beginning, heck, even before an arrest is contemplated, the policing arm of the state makes a determination often on and substantially based upon profiling the subject. That is to say, police as supported by the prosecutorial arm of the justice system, are given a very wide berth in whom they are allowed or not allowed to question in regards to probable cause or reasonable suspicion, so the area of town that you are in, the car that you are driving, the clothes that you are wearing, the people that are congregating around you, and so on and so forth, are all germane to the stop, frisk, and questioning to begin with. This means that if you are part of a group or look that appears respectable in every way, you probably won't be bothered nearly as much by policing agencies than those that appear to have the accouterments and behavioral patterns that the state has implicitly or explicitly designated as targets to harass.
One of the main problems with being stopped and frisked, or stopped and questioned, is that if police officers just don't really like you, or whatever, some very bad things can happen to you, to which, the beginning of those bad things begins with being arrested, so that even if, no formal charges are ever actually applied to you, your freedom and time has been curtailed, and things get progressively worse if formal charges are made. On the other hand, those that are seldom stopped or never stopped, don't have to worry about such things, and not surprisingly, since they aren't harassed except under the most extraordinary of circumstances, have a tendency to follow the adage of "out of sight, out of mind".
Those that are actually arrested and charged with a crime, will next have to face the determination of their bail, and it is this setting of bail, that truly demonstrates that the Constitutional rights that we believe all citizens are entitled to, are in fact, structured under today's justice system, into a stark and bleak situation, to wit, if you have money, access to money or credit, and your crime is relatively minor, as most arrests are, you will probably be set free via bail, and although there will be many more hurdles to overcome, you are able in most circumstances to get back to your everyday life with a relatively minor dent to your everyday life. On the other hand, if you are indigent, or unable for whatever reasons to post bail, even if the bail amount appears fair to the judge, the lack of being able to post bail, means that you will be effectively sentenced to jail time for a crime that hasn't even been adjudicated. This often means, the lost of just about everything that you had of substance to begin with, such as your job, your apartment, your possessions, and so forth, in which, had you the money or had you not been arrested in the first place, none of this would be happening.
In America, there are many wonderful rights that are supposed to be equally applicable to all, but in practicality, there is a monstrous divide between those that have or have good access to things that will aid them, and those have not, and can't access much of anything. This signifies that being poor and/or living in poor neighborhoods is effectively a crime, and America makes those that live under such conditions pay for their lack, by being placed in jail against their will each and every day.
