Lawyers can take various steps to attack the credibility of witnesses (known as “impeaching” a witness ). There are a few basic methods that can be used to discredit witnesses: 1 Cross-examination. After a witness has testified, the lawyer for the other side can cross-examine the witness, asking questions meant to elicit answers that could raise doubts about the witness’s credibility. 2 Other witnesses. Whenever possible, attorneys will try to call other witnesses whose testimony contradicts or at least calls into the question testimony by a witness for the other side. 3 Outside evidence. Lawyers may also introduce outside ("extrinsic") evidence that isn’t directly related to the case but is relevant to a witness’s credibility, such as documents showing the witness’s financial interest in the outcome of the case, social media posts showing that the witness is friends with the defendant, or the witness’s criminal record showing prior convictions for felonies or crimes involving dishonesty. State and federal courts have different rules on what kinds of extrinsic evidence may be used to impeach witnesses.

Evidence is any type of proof that can be presented during a trial to convince the judge and jury of facts in the case. This includes oral testimony, documents, public records, and objects. To get evidence thrown out in court, you’ll need to prove that it’s unreliable, prejudicial, or not authentic.
Challenge a witness’s competency. A witness is only competent to testify about an event if he has personal knowledge of it. Object to any witness who begins testifying about an event without first establishing that he observed it.
You can throw out evidence of a character trait if it is offered to prove that you acted in accordance with the trait on a particular occasion. Courts see this evidence as inherently prejudicial and irrelevant.

Propensity evidence may, however, be used to prove motive, opportunity, intent, preparation, plan, knowledge, identity, absence of mistake, or lack of accident . A classic example is to prove “modus operandi”; that is, a criminal’s unique way of committing a crime.
Move to strike evidence that lacks a proper foundation. A document cannot be entered into evidence unless someone lays a foundation for it. This means that the person offering the evidence must produce testimony sufficient to prove that the item is what the party claims it is.
Witness statements are a crucial part of any case. Their purpose is to show the case in its strongest light. Indeed, a case may be won or lost on the strength of the witness evidence and (assuming the case goes that far) the performance of the witness at trial.
If a witness makes a false statement without an honest belief in its truth, he may be found to be in contempt of court and held liable to pay a fine or imprisoned.
The mere fact that the witness is insane or mentally ill does not make the person incompetent to testify in a legal proceeding. Courts have repeatedly held that the testimony of any person, regardless of his/her mental condition, is competent evidence unless it contributes nothing whatever because the witness is wholly untrustworthy.
The Federal Rules of Evidence are applicable to a proceeding in federal court to determine the defendant’s mental competency to stand trial. Many state statutes declare that persons who are of unsound mind at the time of their production for examination cannot be witnesses [xi].
Competency of a witness is generally assessed through the examination by court or counsel in the presence and under the direction of the court. Such examination is made with special reference to the scope of the inquiry and the subject matter about which the witness is to testify.
A person who can apprehend the obligation of an oath and is capable of giving a fairly correct account of the things s/he has seen or heard is competent as a witness, even though s/he may be afflicted with some form of insanity, is mentally retarded, or is merely ignorant or uneducated [xii].
One of the main causes of wrongful convictions is eyewitness misidentifications. Despite a high rate of error (as many as 1 in 4 stranger eyewitness identifications are wrong), eyewitness identifications are considered some of the most powerful evidence against a suspect.
As we walk down a busy street, it is impossible for our brain to interpret everything we see. In fact, our memories take in bits and pieces of the information and process the important aspects. So should eye witness testimonies be concrete evidence? Details like a stranger’s height, weight, age, and hair are often overlooked. Later, when the police ask a witness to recount specific details of a suspect, we do not have the ability to rewind a video in our brain to figure out what we saw. Instead, our brain fills in details we cannot recount in an effort to recreate a full picture. This often results in bad eyewitness identifications.
Poor eyewitness identifications are a problem across the country but reforms are possible. New Jersey has instituted eyewitness identification procedures across the board. The guidelines call for the double-blind administration of photo or live lineup identifications. Moreover, the admissibility of all line-ups in New Jersey courts is contingent on the administration of the identification procedure being recorded. In addition to these changes, the sequential presentation of an unlimited number of photographs would result in far fewer wrongful convictions cases as a result of eyewitness identifications.
Witnesses commonly testify as to their focus on the perpetrator’s weapon. Typically, a witness can recount the exact color, size, and shape of a gun or a knife pulled on them. What they cannot do, however, is reproduce the perpetrator in their brain.
When an individual is placed in a high-stress situation, their ability to accurately observe and later recall events is diminished. For example, if someone is confronted with the sound or sight of gunfire during the night, the typical reaction is to look for the gun first, then find cover. The high stress of the event puts the witness in survival mode, and makes it much more likely that the witness will be unable to accurately recall an event later. Any traumatic situation, such as an assault, murder, rape, or robbery, will make it much harder for a witness to identify the perpetrator.
Jury duty, as much as some people dislike, is still an incredibly important, incredibly fundamental part of our justice system. Jury duty empowers ordinary citizens to decide another citizen’s fate, and that’ s a powerful ability indeed.
The jury is far and away the most important part of a trial. As I wrote in my last post on the judiciary, the judge decides what evidence goes to the jury and how that evidence is framed, among other things. Regardless, it’s still the jury who decides the final outcome. In that sense each attorney is a supplicant, ...

You wouldn't go to an auto mechanic if you broke your leg, and you wouldn't go to the hospital to have your car repaired. This is an obvious point: Look for websites that specialize in the kind of information you're seeking.
Articles or studies whose authors are named are often—though not always—more reliable than works produced anonymously. It makes sense: If someone is willing to put their name on something they've written, chances are they stand by the information it contains. And if you have the name of the author, you can always Google them to check their credentials.
