The Hough Riots were in 1966, the Watts Riots were in 1965. President was LBJ a Democrat from Texas. As I recall the media coverage was widespread on Watts and not as widespread for Hough. There were only local newspapers and three TV channels to overdose on coverage. I don't recall LBJ being blamed for either of those events.
Thanks to smartphones, the internet, and 24 hour news coverage it is possible to raise and feed paranoia from media overdose! It would be interesting if the truth of who looted and burned in Baltimore and why will ever get the same high level of media coverage. Not as interesting to the average viewer.
