A greedy two-faced cop try to come back on the straight way after his wife is killed in a false police action organised with other corrupted cops.

This doesn't give us a story as such and more of the way a man will feel when something bad happens. It needs to say 'When a corrupt cop's wife is inadvertently murdered.....' and then go on to say how he will feel and what he will do to get over this. We need the log line to tell us the protagonist's journey, what will stop him from going on it and what he will lose if he doesn't make it. At the minute we have the catalyst but not the journey.
