This is an interesting video about the St. Valentine's Day massacre and ballistic examination of the recovered bullets.
One complaint about the video, at 10:05 they show an image of a later Thompson SMG (look at the bolt handle)
According to the video:
*The Tommy Guns used are still in the custody of a sheriff's dept in Michigan and nobody was ever convicted of the massacre
*The killers fired 70 rounds from two Thompson SMGs, 50 rounds from one and 20 rounds from the other
