I had not heard anything about the movie before I watched, and the storyline overview didn't really provide enough information to determine the movie's direction. I figured this was either going to be a propaganda piece, supporting the blue or BLM. Thankfully it was neither.
The movie provided a realistic snapshot in time of our culture. The justice system should be free from public influence and 'A Shot Through the Wall' painted that photo perfectly.
The acting was genuine and believable from the main characters all the way to the extras. It did an outstanding job showing the culture of the protagonist and his family, highlighting the differences between generations. It effectively touched on the minority perception of police enforcement without being judgmental. It touches on the different perceptions of gun ownership without choosing sides.
I would have given the movie 9 or 10 stars, but it failed to humanize the victim and his family, even with a nod towards them in the end. It could have delved into the lives of the victim's family a bit deeper. I think that's a big miss that separates this from being a REALLY good movie to one that's deserving consideration of an Oscar.
I hope this convinces you to watch. It'll be an excellent use of your next 90 minutes.
