|Screen capture from video. Green sign is Jo Anne Fabrics. The tornado is in the background but|
appears to be just a dark gray cloud mass.
The video is below. "Can we not break the law?" they ask as they are hung up at a stoplight (that was torn down by the tornado). "Would the Home Depot be a good [shelter]?" The Home Depot was destroyed with multiple fatalities.
The video is below and I recommend you select HD. Video demonstrates -- again -- the tornado was not recognizable visually as it moved across the city.
Put another way, just about everything you see in the video from :35 to 2:33 was destroyed. When they are stopped at the light (roughly 1:00 to 2:00), they are pointing the camera right at the tornado but it is just a dark gray cloud mass.
