I recommend "FBI Miami Firefight: Five Minutes that Changed the Bureau" by Edmundo and Elizabeth Mireles. Ed Mireles was the FBI agent who ended the fight by shooting both the suspects with a 12-gauge Remington 870 shotgun and his Smith & Wesson revolver - after having been shot twice. It breaks the gunfight down and is an interesting look into what one might experience if one is ever in a gunfight. Particularly a gunfight where everyone is shooting within just a few feet of each other. It will also show what is involved in the recovery process, after having had bullets put into one's body.
