There were only a couple of things that stood out to me during voir dire: after they told us it was a murder case (murder is no longer a capital crime in my state), they asked every juror if they would have problems judging a case based only on circumstantial evidence (there was no video evidence and there were no witnesses), and if anyone would be prejudiced if the defendant never took the stand. I'm sure all the usual questions about neutrality, etc. were presented, I just don't remember them.
It's hard to believe there are still people who think having a witness take the stand in their own defense is a good thing. The only trial I've been in where that happened, the witness did what every defense attorney fears: he made things worse for himself than they were before (and things were pretty bad: it took us less than half an hour to convict).
