I agree that LM likely has a long list of wants, and regarding the request for a laptop with limited access, his attorneys are saying that there are so many documents and videos, etc. from the prosecution that there is no way that they can sit down with LM and review all the material with him, hence a laptop would allow LM to review the prosecution's materials (documents and videos).
The Sixth Amendment of the Constitution does guarantee a criminal defendant the right to participate in his/her own defense, and so LM actually is a member of his defense team in that regard. But whether or not he should have a laptop to review materials should be considered, IMO, in relation to what is the norm - do other defendants have this right to a laptop to prepare for their defense or not? And under what circumstances? I think that precedent should be reviewed by the judge in the case with arguments from both the defense (LM and the attorneys representing him) and the prosecution.
