Debating: "There should be a DNA database for criminals" - This is an arguement for the Negative team.

We have all heard about the wonder applied science of deoxyribonucleic acid fingerprinting. It sounds exactly what we need for our society; however, the reality of tolerate is somewhat less spectacular. First of all, the deoxyribonucleic acid database is non faultless. It is subject to errors and pollution in each of its stages and requires extremely high lab standards to be successful - Just one slight error and the retort could be completely different. One example of this happening was in Christchurch, New Zealand, where a man spent 4 months below police investigation for a double murder because of cross-contamination between 2 different DNA samples. Heat, sunlight and bacteria crapper all corrupt any genetic data, as wellhead as human error or fraud, thats why DNA visibilitys arent always accurate. Even a complete DNA indite can non determine the length of time a suspect was symbolise at a crime scene or the arrive across in question. Also, scientists have warned that as the database grows, the chances of finding 2 large DNA profiles which appear the same and are not actually from the same person will increase. A vocalism from the rhetorical Science Service says that it is slim, but possible. Whats to stop a woeful from collecting samples of blood, hair or saliva from psyche else and displace it at the scene of the crime. A criminal could contribute into a shop and smear someone elses blood on the baffled window to deceive the police, and leave. An innocent person could be a suspect. DNA evidence is far easier to plant than someones fingerprint; wherefore DNA testing should be no substitute for hand down detective work But not only could there be overturn contamination from the criminals, Police could be touch on in deliberately drylabbing or faking DNA results. In 1995, an 18 month investigation was launched... I personally th ink a DNA database would be useful, but I co! mpletely show what this esay is trying to say. It is a practiced arguement for the negative team in this debate. If you want to get a full essay, order it on our website: OrderEssay.net
