I'll agree to disagree on this. The still pic of him has been out there for over two years and NO arrest. Posture, clothing, stance all visible. It would appear no one has recognized him thus far or if they have, they're not telling, for whatever reason and THAT person is unlikely to reveal him now regardless of the video. His voice has been out there for over two years and NO arrest. LE had to swallow a bitter pill before that PC on April 22nd and releasing the "new" sketch. If anything, it's more likely the sketch will bring in more fruitful tips, or at least we hope so. He needs to be found.....yesterday!What LE is asking is not mutually exclusive. You can totally have it both ways because again - what they are asking is not mutually exclusive. It's still possible to see BGs movements and recognize them. LE is making the point that the perp does not walk with this gait at all times (because of the terrain) so ignore his exact gait in the recording. "Oh that movement/body/clothes/posture really looks like my coworker but he doesn't walk like he is walking over a dilapidated bridge so I guess it can't be him." People tend to get close minded and will stop looking outside the box because it's easier. Sometimes people need simple instructions.
I assume you don't know BG so his movements do not look familiar to you. It's not useful to *you*. To someone else that does know BG, this video might make all the difference in the world in recognizing him. I do not think you would necessarily need a full face, walking straight, clear as day picture to recognize him if you knew him.
