Why
Do Police Erase DUI Videotapes?

Many
law enforcement agencies use videotapes to record a DUI suspect's
driving, appearance, demeanor, slurred speech and/or performance
on the field sobriety tests. This taping may be done with a camera
mounted in the police car, or with one at the police station (if
there are no dedicated recorders at the station, experienced defense
attorneys often try to obtain tape from the security cameras).
It
is common to encounter situations where a suspect was videotaped
but the tape was later erased (the legal term for this erasure is
spoliation). This is sometimes done accidentally. Unfortunately,
it is often done for a more insidious reason: the tape shows that
the arrested person may not have been under the influence -- his
driving was not erratic, his speech not slurred, his balance and
coordination on the field sobriety tests not impaired.
There
is a string of United States Supreme Court decisions which deals
with the consequences of lost and destroyed evidence generally (Brady-Agurs-Trombetta-Youngblood).
Roughly, these decisions require any material evidence to be turned
over to the defense if it is requested by the defense. Even without
a request (the defense may not know about it), evidence must be
turned over if it is exculpatory -- that is, if it could have played
a material defense role. The loss or destruction of exculpatory
evidence constitutes a denial of due process. If the evidence was
not clearly exculpatory but was still "potentially useful",
it is a denial of due process only if the loss or destruction was
done in "bad faith" -- that is, intentionally or for the
purpose of denying the defendant access to it.
The
burden of proof is on the defendant. The Catch-22, of course, is:
How do you prove the erased tape was exculpatory if it has been
erased? Or that the erasure was "potentially useful"?
Or that it was erased in "bad faith"?
Because
of these usually insurmountable hurdles, some police officers continue
to erase videotapes when those tapes contadict the damning descriptions
in their arrest reports.
