Conditions for racing in Los Angeles are far, far better than in Texas, so let's put that to rest. What Hassan did here was, like Naser in that women's 400m final (48.14), literally incredible. I'm not as worried about the times of the others just because they had an absolutely amazing pacemaker who allowed them to take off at a moderate pace and just gradually upped the pace every lap so that they got to maximize by drafting the entire way, except for the 2nd place when Hassan took off the last lap. If Hassan was a 3:56 runner and now she dropped five seconds on her own, after two heats and a 10000m race, I just cannot imagine that she is clean because that puts her squarely in Chinese and Eastern European doping territory and she might very well have been able to beat Genzebe Dibaba's wr of 3:50 fresh and with a pacer. In fact, with a male pacesetter going the whole way, I am sure she could get into the high 3:40s (which wouldn't count). It's just nonsense.
