my problem is with the use of digital cameras and digital images as sole
evidence. It's too easy to alter them.
I was following a car the other day, and with the nature of the font
(although
AFAIK perfectly legal when it was made) and the presence of damage
to the top of the plate making a U look like an O, it could have been
interpreted easily as SOO rather than the SDU that it actually was.
Depending on the quality and clarity of the image, it might well not be
possible to tell. If you use image enhancing software on it, then the
software make an arbitrary decision that this or that pixel should be black
or yellow (OK, that's a crude approximation, but you get the drift) and you
can't tell me that it always gets it right.
That's without considering the possibility of tampering with evidence. Not
saying that the evidence *would* be tampered with, merely the possibility
that it *can*, without being detectable, is enough to make the evidence
unreliable.
