In United States v. Blouin, ARMY 20101135 (A. Ct. Crim. App. 28 May 2014), the court has, in my view, taken a broader view of what qualifies as CP for the purpose of a guilty plea. However, the court is not taking an unknown or unvisited trail.
Blouin was charged with possessing CP in violation of 18 U.S. Code Sec. 2256(8), to which at trial he plead guilty.
As is common in these type of cases, the prosecution threw up a whole bunch of alleged (173 to be exact) CP images, without really understanding what they were doing. And they compounded this with offering 12 images as a “sample.” This caused the military judge to reopen providency, because he found only three of the images were likely CP.
