We should be clear that many (most?) of the immigration raids you are describing are taking place in cities that have explicitly stated that they will not cooperate with the federal government regarding immigration, meaning that anyone in these cities who interacts with the police or justice system (generally speaking, in most cases) will not be reported for being in the country without documentation. This means that the federal government has fewer means of detaining individuals without documentation in a safe manner, even those convicted of serious crimes. We see the result of these policies now.
