Clearly they didn't fear that he was a flight risk or they would have or should have acted sooner. I'll bet the depositions that have been ongoing since May 14th have not been going well for the prosecution, and this was their temper tantrum.
Heh. It is an odd case that way. The Sanford Police and the most reliable on-scene testimony all supports the accused. The testimony of the police contradicts the state's theory of the case. The state uses DeeDee and Sybrina's voice analysis, in combination with conjecture, to make its case.
I don't see any way the depositions could possibly go well for the state, and they are idiots if they thought otherwise.
