OR - why did you need a gun when there were those guys on the roof?
Sort of like, why would you need a gun when you could always call the police or social workers, if you felt threatened?
I am concerned about the defense being so quiet, but probably they are planning on some detailed and extensive redirect? (is that the right terminology?)
Yep. Direct exam, cross exam, re-direct, re-cross, re-re-cross, and so on.
Supposed to be be no “new material” unless brought up by direct, re-direct (the witness’s lawyer)
Yep, why do you need a gun in your home if you have never been robbed or attacked?
