Cultures and systems can select for biased treatment of groups even when looking exclusively at the local segment of a larger system which happens to have black decision makers. If you look out your window into America today and don't see systemic racism either statistically or with your own eyeballs I honestly don't know what to say to you.
The topic of discussion is a company that produces a product that due to echos and analysis doesn't actually know where or if guns are fired being deployed in shitty crime ridden neighborhoods where disproportionately minorities being poorer are obliged to live. In the context of the gun shot imaginer system they have been literally caught doctoring data to match what the police wanted to be true in order to obtain a conviction.
Multiple things can be true. The shot spotter can be deployed in areas where gun fire actually and truly is more common, it can be misused to shake down or frame people in that area, such behavior can primarily be misused against people in that area, because more poor black people are obliged to live their they can in turn fall victim to such bad behavior more frequently even if not specifically targeted by law enforcement. Further faced with multi decade scare tactics and shitty public defenders poor people and by extension disproportionately minorities flinch and cop pleas.
This is how you fill your prisons up with black people.
This is literally what systemic racism means. Its a racist outcome of a fucked up system even when said system isn't consciously malicious and lets be a little honest with each other. We both know that there is plenty of honest bigotry. There are plenty of folks in government and plenty of folks in uniform that wouldn't mind donning a sheet and burning a cross in their neighbors lawn.
America was born in racism and as much as we hope to generation by generation make it more equal some of us remain more equal than others and a lot of us like it that way.
