AGRBear-
I can't quote and answer for reasons of length, so will clip the quote when finished-hopefully it doesn't mess up the format.
I'm not quite sure what you mean by "Cheka claims." The Cheka never made any claims. What we have are the statements of guards who heard about the shooting, or witnessed it, and the statements of those who participated (of whom only 3 were in the Cheka).
One problem is simply taking published works and what they say-for example, both Radzinsky and Massie either didn't know about or have access to Yurovsky's 1922 memoir and Victor Netrebin's statement, or the complete text of Kudrin's statement, and those of Isai Rodzinsky and Alexander Strekotin. What we did was return to original primary accounts to determine the number of shooters and who they were. I'm confident that they were 10-we lay out all the details, previously published versions, and arguments in "Fate of the Romanovs."
Radzinsky's photo of Beloborodov, Goloshchokin, et al., does NOT reflect a picture of ANY of those who shot that night. The shooters were: Yurovsky; Kudrin; Nikulin; Ermakov; Medvedev; Soames; Netrebin; the two Kabanov brothers; and Lacher. Of them, Yurovsky, Kudrin, Nikulin, Ermakov, Medvedev, and Netrebin were all ethnic Great Russians; Soames and the two Kabanovs were Balts; Lacher was an Austrian, and the only foreign shooter.
My point is: it's important not to turn to what Radzinsky said, or Massie said, but to what the original statements and memoirs say. We may be at variance with "accepted" thought on the number and ID of the shooters, but we do so based firmly on the eyewitness accounts and statements, many previously unavailable to other historians.
