If anyone on the defense team is reading Websleuths, they must be quite giddy with how much controversy this DNA on the glove box is creating and banking on it creating a lot more confusion for jurors who probably don't follow true crime.
Hopefully they are also aware of how quickly an expert could explain very clearly and simply why the DNA on the glove box is totally irrelevant.
If that is their strongest piece of defence evidence then they are in trouble keeping BM a free man.
