Mr. Shawn Rettsatt of the USA
Shawn Rettsatt has been judging for years. If he was scoring people to undermine competitors, certainly he would have had a talking to by now.
There's also a judge or two that is outside the corridor and they may have a valid argument with how they ended up there. In the end that person's score doesn't matter because they are thrown out in the final calculations.
ETA: If there's some history of him scoring V/M low in past events, then perhaps there's validity in the assumption, however please point that out rather than throwing generalities.
ETA2: Okay, apparently there was a judge at the 2011 4CC that gave V/M 5s in PCS and it happened to be that Shawn Rettsatt was on the judging panel. However correlation=/=causation. Unless it's been publicly declared somehow, there is no way to prove he was the judge in question in either situation. It's speculation at best. http://www.isuresults.com/results/fc..._SD_Scores.pdf
Oh by the way Jodi Abbott, the judge from Canada was also on the panel for both events. Perhaps she did it to ensure her favorite Canadian team (W/P) had scores closer to V/M.
But in the end, again, it doesn't matter because the scores were thrown out.

In the FD, unlike the SD, SHAWN RETTSTATT (USA) was not drawn to judge on the FD panel. And surprise, surprise. In that segment, V/M didn't get lowballed by a single judge. In fact every single one of them gave them at least a 10.00 somewhere in PCS and all marks across the FD panel were consistently in the mid to high 9s - 10s: http://www.isuresults.com/results/wc..._FD_Scores.pdf
I think it's hilarious whichever judge gave V/M 5s in all PCS marks at 2011 4CC, though. Shawn Rettstatt or not, seeing those numbers on paper is pretty funny You'd think that she or he would know better and might actually be asked to provide some explanation in the roundtable discussions.
You mentioned that "But in the end, again, it doesn't matter because the scores were thrown out". But when marks are so close between V/M and D/W, it does make a difference. At this particular GPF in Japan this one judge's marks for V/M were glaringly obvious in both SD and FD (8s?) that I hope is looked into.
I think someone posted here that Shawn Rettstatt will be the US Olympic ice dance judge in Sochi. Oh Goody. When that time comes I'll keep my eyes peeled for a set of marks given to V/M that rivals that of Chock/Bates
