As previous posts have mentioned, drug charges can result in serious consequences if the accused is convicted. Charges such as drug possession, trafficking and distribution counts may lead to large fines and jail time. In some instances, prosecutors will rely on witnesses to testify against the accused.
However, the testimony of a witness can be severely undermined when the witness' credibility is brought into question. Texas residents may know that former Houston Astros pitcher, Roger Clemens, is currently on trial for allegedly lying to Congress about illegal steroid use. However, the trial was recently focused on a key witness, the alleged-steroid dealer of Clemens' strength coach.
The dealer testified that he supplied drugs to Clemens. However, this convicted drug dealer wrote a book called "Bases Loaded" which is a personal account of his alleged-steroid dealings. Upon taking the stand, Clemens' lawyer brought the dealer's credibility into question by pointing to inconsistencies in his testimony at trial, as compared to what he wrote in his book.
At trial, the dealer alleged that some crucial evidence found after a search of his home was unbeknownst to him, accidentally swept under his television. Clemens' attorney pointed to the text of the book which instead indicated that the dealer intentionally hide the label in question from the police.
Clemens' trial is ongoing. Crucial testimony from his coach, who allegedly injected him with steroids, will occur within the next few days.
A strong defense is crucial in any situation which involves drug charges. A solid defense can include addressing the credibility of a key witness when appropriate. While the prosecution may bring a witness to testify against an accused, that does not mean the testimony is truthful or accurate.
