mike is making what is a common error in reactions to these events - he wants retribution, which he calls "justice". so, he wants to go after the prosecutors. he wants to send these "bad apples" to jail. it's the same response you see over and over...

but, what is the point of sending these cops to jail if the academy just replaces them with four more that think exactly the same way?

this is systemic, and you have to go after the root causes, which are in the way that police are taught to act. it's not an accident that this happens over and over - it's the system. they're not "bad apples". it's by design.

i know you don't want to think of it like this, but sending these cops to jail isn't any more useful than sending some low level crack dealers on the street to jail. it addresses something emotional, it expresses something religious, but it is an absolutely useless step in actually solving the actual problem.
