You think black judges go soft on black defendants who cry "racism" as a reason for their criminal activity? That's why "because slavery" is such a stupid argument from the "All police are racist" crowd. That **** may work on CNN, but it does not play in court. As a public defender, you should know that better than anyone.
If you really want to know my experience in criminal law, feel free to send a private message.
On the other hand there is something at play I have seen also at play with north african in france : disproportionate check or arrest for the same activity among non-white compared to white.
I will give you two examples that I understood are valid in the US statistically.
1) being controlled nwhile being non white
2) being arrested for minor offense as being non white
For point 1 , there was this tigma that if you were non white, you better got driving a cheap car or not driving at all, because driving an expensive car would get you controlled more often than other people. Same while walking around. It was not funny the first time as I a caucassian was not controlled for paper while my 2 friends were, it was not funny the xx
th time either. It was not funny seeing them often asked to show their backpack in supermarket (I was not). One of my own friend being a policeman in north banlieu paris simply admitted to racial profiling because everybody else was doing it and it seemed to work.
For point 2 : I have seen policemen ignore jay walking right in front of their face of white guys, only to see one non caucassian get immediately a minor fine.
Look I am very warry after that of statistic because if every body no matter the melanine amount in their skin are doing the same minor offense in proportion, say 25%, but say non cauccassian are controlled or fined far more often, this alone will skew the statistic. And give a feeling of racism and injustice. And yet none of the fined can say they were innocent. It is just the difference in attitude and the levity of police to not pursue some illegal activity which can simply skew this.
Those might have been only anecdote, and not representative of the whole situation in France but I doubt it.
If I had to give a guess not knowing the situation that much in the USA or fergusson, I would say this might play a role.
