I think I heard it might last 4 weeks. At this point, if the Prosecution doesn't come up with better evidence than they have presented so far, then the Defense should make a motion to dismiss the charges at the end of the Proscution case. Doubt if the Judge would do it.

I think it's rather obvious judge would not do it. I presume that's why defense didn't even to for a stand your ground hearing.
