president lee seems to be
about to support the idea of leading and taking.
dna samples
from the bad people
for a crime
but not convicted
that is,
putting good people's dna
in criminal databases.
advocates of expanding criminal databases argue
that including good people's dna
protects communities
and saves lives.
this is the "more better" approach
to crime fighting
the more dna files are coming out
from the crime
as for being innocent,
nothing to worry
about if you didn't do anything
the bad things
right?
some people says
there's no differents
about doing bad or good thing.
not so fast.
dna forensics involves
complex statistical calculations
and requires extremely
careful handling
to prevent errors
sample contamination
and other problems have been well documented.
take,
for example,
a 2005 examination of Arizona's criminal database
the entire enterprise of dna data bases is based
on the idea.
that no two people share the same profile.
but Arizona's database of 65,000plus
entries was shown
to have more than 100 profiles.
that were similar enough
for many experts
to consider them a "match"
