“Cross-examining Trial Attorney & Toxicologist Okorie Okorocha is like a knife fight in a phone booth & results in the cross-examiner taking an incredible beating! On the other hand, getting cross-examined by an attorney that know far more about the science than the witness is the witness’s worst nightmare.”
