Announcing the grand jury indictment or lack thereof at 5:30 pm plays into the rioting being greater than it would otherwise be.
This is kind of like airing the big game so as to get the biggest audience in all four time zones.
I guess there will be gridlock on the Los Angeles freeways as folks bail out of work at 2:30 pm to riot.
That would be 3:30pm..
Just picking nits...
