Locard's Exchange Principle |
Even with the continuous research on wrongful convictions and the increasing number of exonerations, some states have failed to change
their legislature on the preservation of evidence. The act of preserving
evidence is vital in exonerating an innocent person.
According to The Innocence Project, not all states have laws
that require preservation of evidence after conviction. The states that do have
this legislation, however, have not dealt with the limitations of their laws. For
example, some states have a specific time frame in which evidence should be
preserved. After that time has passed, the evidence is allowed to be destroyed.
Other states limit the evidence that can be preserved according to the type of
crime that was committed. It seems that these states are more worried about storage
space than upholding justice. Think of how many innocent people are in
prison right now just because the evidence to prove their innocence was not preserved.
It is unfathomable.
There are a few solutions proposed by the Innocence Project,
which involve amendments to current legislation. One amendment could be
preserving and keeping evidence from the time an individual is convicted until
the petition is made to prove their innocence. Another amendment is to allow for
a new trial if evidence was destroyed. If the jury finds that the destruction
of evidence was intentional, then they can presume that DNA testing of the
evidence would have been exculpatory.
