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.
Why is DNA important in crime scenes?
The DNA of each individual is unique. No two individuals share the same genetic make up unless they are identical twins.

If it can be legally proven that a suspect was present at a crime scene, there is practically no refutation to this finding. DNA test data is very valuable in court. But if you were never at the scene of the crime how can they prove you were anyone could have put it there?
