If I was going to wage a guess, I'd say he waved his right to a speedy trial. This would then give everyone plenty of time to prepare their case, or for the defendant to give up some big guys (if he was offered a temporary position working for the good guys as an informant)
So if he is not brought to trial by August, the case would still be pending and he wouldn't be released because of his rights being violated.
This is just my shot in the dark. But I'm interpreting the "NO RST" to mean NO Right to a Speedy Trial.
If you pick up a starving dog and make him prosperous, he will not turn and bite you for your kindness, but he will stand by your side until death.
This is the principal difference between a dog and a man.
