I saw the trailer and noticed that they had the correct side arm for the time. Same type I was issued, a 10-5.
I'm not too happy to see that movie come out as it was a sad time for Detroit. The Alger's motel shooting was questionable and I'm sure it's not going to be a fair minded effort on the producer's part to portray it.
The whole 1967 Riots rang the death knell for a once great city. No need to open up old wounds but money talks and .............you know the rest. Keep the pot stirred up.
