Knit Tie will likely say that the whole thing is heavily redacted but I doubt it.
Why not Sergarr or Guardian?
Anyway, the difference in reactions is not surprising in the slightest, as it is not due to the horrible inhumanity of the despicable katsapy and the nobility of the Caucasian warriors, but rather due to the fact that Caucasian people constitute a minority in most Russian societies that frequently comes under attack from various less desirable elements, and as such most of the Caucasian diaspora in Russia is very tightly knit and learns quickly to look out for its own. Russians, on the other hand, exhibit the typical reaction of modern city dwellers - indifference towards those whom they don't personally know. The experiment is thus biased due to the dependent variable, reaction to percieved aggression towards a member of their national group, being affected by more than the independent variable, nationality, and so I wouldn't consider its results to be objective unless they are confirmed by a string of similar experiments in different environments, such as a Caucasian-majority city, a Russian village, a Caucasian village and maybe even a small provincial town on the border of Dagestan where the numbers of Russians and Caucasians are approximately equal.
EDIT: I took a look at the youtube channel that made the video that UR is linking, it's a bit vacuous and platitudinous, but
here's a video of most Russians in Moscow being willing to help Ukrainian refugees.
