Numerous lines of evidence such as video footage, photographs and witness statements may be used at trial. Forensic evidence, toxicology reports and cellphone records may also be used depending on how relevant they might be to your case. There is also a chance that the officer who took you into custody as well as others associated with the investigation into your activities may be called to testify. Finally, you may be called to testify at your trial in an effort to convince the jury that you should be found not guilty.
