DiEugenio's review, when I read this (from part one):

Three "master marksmen" took two tries at duplicating what Oswald was supposed to have done. Now what does this qualification of "master marksman" mean exactly? As Meagher explains it, they were rated at the very top of the scale, not by the Marines, but by the NRA. In other words they were even better than the top shooters in the armed services by a level of two or more classes. In fact, they were so proficient they qualified for open competition and even the Olympic Games! Now compare this to Oswald who was one point above the minimum class possible when he left the Marines in 1959. Fair comparison right? Further, while these men practiced all the time, there is no known credible witness who saw Oswald target practice with the rifle in question. So right off the bat, one would have to wonder why the Commission had the military pick these guys and not a shooter more comparable to Oswald. The results as displayed by Meagher show why. Of the three men only one of them bettered Oswald's time. But here's the catch: they cheated. Oswald was firing from 60 feet up at a moving target. The three experts were firing from thirty feet up at still targets. As Meagher notes, wouldn't it have been quite simple to just rope off Dealey Plaza, put these guys in the sixth floor window, place a convertible in the street below, and try a true experiment? If this was not done, why was it not done? Neither in the text at this point, nor in the corresponding End Note section does Bugliosi tell you about the different settings or pose the question as to why they were not the same. But several sentences later, after giving the reader this incomplete information, he pillories the critics as being "so outrageously brazen that they tell lies ... about verifiable, documentary evidence ... " (p. xxviii) A few pages later, in discussing how the critics have sliced and diced Gerald Posner's book, he comments they are "going to have a much, much, much more difficult time with me." (p. xxxviii)

But even these "successful" (however forced that label may seem) experiments are contradicted:

In fresh tests of the Mannlicher-Carcano bolt-action weapon, supervised by the Italian army, it was found to be impossible for even an accomplished marksman to fire the shots quickly enough.

The findings will fuel continuing theories that Oswald was part of a larger conspiracy to murder the 35th American president on 22 November 1963.

The official Warren Commission inquiry into the shooting concluded the following year that Oswald was a lone gunman who fired three shots with a Carcano M91/38 bolt-action rifle in 8.3 seconds.

But when the Italian team test-fired the identical model of gun, they were unable to load and fire three shots in less than 19 seconds - suggesting that a second gunman must have been present in Dealey Plaza, central Dallas, that day.

It seems the attempts by the other side to deny the government conspiracy to murder JFK are well funded, and are increasingly absurd, with inflated rhetoric to match.
