I do actually think that in terms of 'how often they do crime' that indeed the poor, whatever race they be, do it the most and get genuinely caught the most (not just unfairly convicted the most). That is, however, ignoring the reason for it. Let's ignore how much money plays a factor in how good a law firm you get to work to defend you in America, just to be clear on what could be different:
In Commonwealth nations the one who does the 'talking' is either yourself or a publically funded barrister, this is unable to be hired by you as such but yes indeed, there's ways to pull strings and get yourself the best one if you're rich and influential enough, basically what you pay for is all the behind the scenes work, the idea is that money can't gain you an advantage once already inside the court room for speaking more or less eloquent English or knowledge of the Law as all Barristers are experts both at speech eloquence and Law, but I don't deny there still is entire monetary advantage considering how much better background work will be done by the best solicitors out there vs the laziest).
I don't actually care about this when I consider myself a Progressive, this is actually not the real issue when discussing crime and the poor. The reason why the poor do actually do so much more crime is not only the most obvious thing ever (I'll go into the other reason in the next paragraph, for now here is the obvious reason); the most people in any nation's classes are the poor to lower-middle class, so population-wise to compare the crime-rate percentage of overall crime between the race that happens to be the wealthiest vs the poorest is idiotic. You see, if you compared redneck-types or their rivals; antifa-types, you'd see that poor and lower-middle whites have a lot of crime, be it more 'organised' as in Mafia and Gangs, or dispersed. In fact, if it comes down to organised crime, the two races associated with lowest crime rate (whites and 'yellow' Asians) are actually consistently are the most deep-penetrating, sophisticated and therefore devastating organised crime bringers to the world as a whole. Whether we are talking UN-level corruption or your local alcoholic thugs, they have a whole range of crime but because they happen to be amongst the richest in the US, their race can say that much less of their race do crime and here is why:
Crime is not only much more optimal, the poorer you are, to get anything worthwhile in life (materialistically), but it also becomes much harder to cover up or work out ways to 'edge yourself' to the very edge of what's legal vs illegal so that you're on the right side of the line in the sand. From getting medical marijuana to begging a loan shark to get you out of a debt that banks don't want to risk on you, being poor gets you dragged into a world of 'sure, you can get what others have for themselves and their close ones, but that material-stimulated pleasure comes at a cost'. With services things are a bit simpler; you can settle for a shit service and suffer through the shit quality, but when it comes to trading goods, it's much harder to settle for something that is so bad you don't get the intended outcome. It's not just about getting high or getting a loan that you can't afford to pay back soon enough, being poor drags you into a lot of situations that other classes never even face, just because you are among poor neighbours, friends etc. You constantly will find yourself needing to keep your mouth shut about things going on, helping a friend sober up and lying about it. If you don't participate in this local kind of 'conspiracy', either the gang kills you for beign a snitch or in less organised crime scenarios, you get a reputation, revenge etc. The problem is that when you're middle class or higher, if your neighbour literally smashes your car to pieces, you will be able to give them their just deserts legally, but if you get into beed with a neighbour and you're dirt-poor who the fuck is going to sue them for you? They'll deny it was them and the other neighbours will even lie, incriminating you, if your street cred is too low. I know you think I'm talking like someone who has never been poor, imagining what it's like, but I can tell you that what I am describing is actually real. When I told some poor people I know about it, they understood it completely and agreed. It actually fascinates me how naive and crap the street smarts of most non-poor people are, they'd actually last longer in the dog-eat-dog world of backstabbing elitism than being poor, since the Elite know how to handle stubborn people without necessarily overtly hurting them, they just make you no longer a real contender for a position of power or level of wealth. Once that's achieved, you're yesterday's news. With the world of the poor, you don't quite understand how it is unless you've truly exposed yourself to the world. What I am saying is as true for a teenage girl who is not involved in any sluttiness or gangs, as much as it's relevant to the forty year old guy running one. When you're in the world of the poor, you are forced to keep your head down, mouth shut and participate at the very least by obstructing justice subtly, at many points. Sometimes the only pleasure you even can fathom in that life is a little high now and again, which gets you dragged into more crime.
