From the Paper:

"Lastly, Smialek, Word, and Westveer note a primary disadvantage of DNA fingerprinting is the ease in which it's contaminated. Samples have to be collected and handled with gloves that have to be changed often. Disposable instruments, or those that are thoroughly cleansed can only be used. Even talking, sneezing or coughing over evidence can make it worthless. In addition, there is the backlog of DNA samples to be processed which lead to lengthy waits between collecting and interpretation."
