Re: 8 - Come on - that’s not when the riot started. You’re missing a whole group of acts that are both violent and otherwise.
There was evidently a high degree of animosity between the two sides well prior to the riot. We don't know if the black crime problem back then was anything like the level it is now.
It is well known (among people who pay attention) that black crime rates are much higher than whites, with blacks accounting for over 50% of all homicide and robbery arrests.
The FBI started doing their “Uniform Crime Reports” in 1930.
PDF of the first series is at

Unzip the zip file, and look at 03666-0001-Report.pdf
Interestingly, near the end at PDF page 1086, it lists the arrest stats by race in 1936, with per-capita breakdowns.
Back then, native-born whites had a homicide rate of 5.0, blacks 31.3. Robbery rate: whites 12.4 black 44.7.
Go down the list, and the black rate (per 100K population) is several times the white rate.
Apparently, blacks HAVE ALWAYS had crime rates several times the white rate, even before the Welfare State could be blames for it.
This could explain the irritation that white Tulsa residents had for their black neighbors.
