Genetic engineering has developed and blossomed at a frightening rate in
the last decade. Originating as merely an area of interest for scientists,
genetic engineering has now become an area of which all people should be
somewhat knowledgeable.
DNA profiling has many uses, both positive and negative, in our society.
Aside from its usefulness in many legal investigations, DNA profiling can be
used in the workplace to discriminate against employees whose profiles could
pose a financial risk. For example, genetic technology can and has been used to
determine the capacity of a person to contract certain diseases, such as sickle-
cell anemia, which could cause many employers to hesitate in the hiring and
training of such people. In the early 1970s, the United States began a carrier
screening for sickle-cell anemia, which affects 1 in 400 African-Americans.
Many of those identified as carriers mistakenly thought they were afflicted with
this debilitating disease. Furthermore, confidentiality was often breached, and
in some cases, carriers were discriminated against and denied health insurance.
Nevertheless, genetic profiling has been beneficial in paternity suits and rape
cases, where the father or the assailant could be identified. However, despite
its growing number of utilizations, DNA profiling is extremely hazardous when
results are inaccurate or used to discriminate.
The frequency of genetic testing in criminal investigations (more than
1,000 in the U.S. since 1987) has been increasing dramatically despite the
inconclusive testing by the scientific community in many aspects of forensic
identification. A correlation between DNA patterns taken from a crime scene and
taken from the suspect has often been enough to charge a person with the offense
in spite of proof that some procedures for testing DNA are fallible by legal and
scientific standards.
The complexity of scientific evidence, especially DNA profiling, has
also caused many problems within the legal profession. It is no longer enough
for attorneys or members of the jury to merely be knowledgeable about the law.
People need to familiarize themselves with todays scientific research rather
than relying on the credentials of a scientific expert witness. Too often, jury
members become in awe of the complicated, scientific terms used in court and
take a scientists testimony as fact. Lawyers need to increase their scientific
knowledge and keep up with ongoing research in order to competently question and
understand scientific evidence put forth.
But these do not represent the only possible downfalls of DNA profiling
in criminology. The involuntary seizure of ones blood or hair undermines the
constitutional rights guaranteed to all citizens by the Fourth Amendment
(protection from unreasonable searches and seizures). Nevertheless, many argue
that a DNA sample taken from a suspect could lead to an indictment or release of
the individual and, thus, warrants an exception from the Fourth Amendment.
Besides, one could make a plausible argument that, once held in custody, the
seizure
