falsification of evidence(False evidence, forged evidence or tainted evidence is information created or obtained illegally, to sway the verdict in a court case. Also, misleading by suppressing evidence can be used to sway a verdict; however, in some cases, suppressed evidence is excluded because it was found hidden or locked away in areas the accused could not be proven to know. In Britain, falsifying evidence to convict the guilty is known as 'Noble Cause Corruption'. Some evidence is forged because the person doing the forensic work finds it easier to fabricate evidence than to perform the actual work involved. wiki Alexander Demidov)
