first off my apologies for not responding to this earlier. I simply didn't see it. I think 3.5 (out of 5) is a pretty good assessment but because of the fact that they made it so long I would probably dock it a full star for having so much filler. The story is solid and the fact that they don't seem to have a political agenda when presenting it is quite refreshing. I liked how they showed that there are reasons why police officers behave the way that they do and much of this has to do with directives they were handed down by politicians. This is probably very true all around the USA and the rest of the world.
They could have done this entire thing in 90 minutes though.
