brother elephant, The trial process should be thorough. It would be hard to tell that on this forum as how "thorough" will be considered as, well, thorough enough. Are you a lawyer? If so, then you should be familiar as what is meant by thoroughness. If you are not a lawyer, then I would suggest to inquiry about the trial and cross-examination process and so forth from any lawyer that you might know. And of course the court will have to use any tools, lawful information/evidence gathering techniques and everything else that's available during the investigation and trial process as to uphold justice. Allah Knows Best.
