All witnesses, including neighbors and police and EMTs and coroner's techs can be questioned in one day. The whole incident unfolded in just a few minutes. There is, essentially, no more information to gather besides what we already know - except, perhaps, the TM's autopsy report (which is likely to tell us nothing.)
IMO, the trial can be all over within a week. The prosecution asserted a bunch of stuff ("profiled", "continued to follow") that would be impossible to prove and quite possible to disprove. Basically, nothing matters among what GZ and TM did prior to the physical altercation. They could look at each other, run away from each other, hide and seek, exchange words... none of that is illegal, and the threshold for stalking is much higher than the prosecutor implies. Otherwise I'd be stalking hundreds of people whenever I go to a grocery store.
Think about this for a minute....
The SOB Muslim Major Nidal Hasan murdered 13 innocent people and had 32 attempted counts of murder in Nov. 2009. Where is the outcry? You can thank the media and Obama for these delays. Now the trial has been postphoned to October 2012. Wonder why?
