So you are saying poor communities only commit more crimes because of the policing?

The "systematic racism" argument is so broad and unquantifiable and avoids so many other meaningful factors that can actually be addressed. It's a way for these communities to avoid confronting any internal problems they have - whether or not these were caused by historic racism, cycles of poverty, etc.

You should look into some stories of how criminals ended up becoming criminals. Present-day racism is rarely the cause.
