Are there any downsides to DNA evidence?
There are a few downsides to DNA evidence: It has been suggested that the prominence of DNA evidence on TV shows has caused juries to expect irrefutable DNA evidence before convicting someone. This may be a problem if other forms of evidence are ignored. DNA evidence can only be obtained in instances where biological substances are left behind or exchanged. This only occurs in a minority of cases. DNA evidence sometimes only proves that the person was present at the scene - it does not always prove guilt. However, if a person's DNA is found at the scene, this may be perceived as proof that they committed the crime.
