Answer:
He is implying that it will be very easy to frame Steve in court.
Explanation:
When Steve's father claims that Miss O'Brien believes that anyone in the tri-state can make Steve stink, he is saying that it will be very easy to incriminate him. Miss O'Brien really believes that, and she doesn't hide it when she says that anyone in court will be able to make Steve "stinky" or be undesirable, disgusting and consequently criminal. Miss O'Brien claims that one of the main reasons for this is that Steve is black, which will make most of the jury find him guilty just by looking at him, which will make it very difficult to clear him.
