Detection dog

Accelerant detection dogs are used by fire departments, and other fire investigators to aid them in the detection of substances used to expedite fires and underscore the spreading of the destructive flames. Dogs are used due to their special skill set in detecting odors that humans are unable to; their ability to differentiate sets of different scents, and locating scents even after some time has passed since those smells were deposited. In 1993, evidence gathered with the help of accelerant detection canines, helped convict five people when traces of flammable fluids were located on their clothing by the specially trained dogs. (United States of America vs. Kathryn Schroeder, ET AL, 1993) Insurance companies such as State Farm promote and encourage the use of accelerant detection canines. Starting in 1993, State Farm has sponsored and financially aided several law enforcement and fire departments with the Arson Dog Program, to help with the apprehension of numerous arson perpetrators yearly. ("Arson Dog Program," n.d.) One of the recipients of the aid offered by State Farm was the city of Ocala in Florida’s fire department, which in December 014, acquired its first fire dog courtesy of a $25, 000 grant from State Farm.

The initial cost to start a K-9 unit is $20,000-$29,000 (Bullington). This figure doesn’t include the maintenance training and general living expenses for the dog, including food and vet care. If there isn’t a spare vehicle that can be converted to accommodate the needs of a K-9 unit, a special one must be purchased. Proper equipment is essential as well. The canine is an investment and must be carefully thought out. It’s not just the material essentials that are expensive; being accountable…

A micro expression is a tiny facial cue that appears within one-fifth of a second. It is uncontrollable and shows an observer signs of every emotion. It shows signs of deceit as well. Usually these are undetectable, but with some training they can be detected and used in investigations. Therefore, facial micro-expressions should be admissible in federal investigations. We need a replacement for polygraphs, and micro-expressions are a fine candidate. The previously used lie detector, the…

The basic definition of a lie is to state something on purpose to a group of people, or even a person, that is false. In order for a person to lie about something that person will need a reason, either to cover something up, to explain something in a nicer way in order not to make the specific person being lied too to feel bad, to hid information that is thought of un important or un necessary, or even to just get out of a situation. There are multiple types of lies, to many to state actually;…

For instance, many paradigms in lie detection studies include memory confounds, which make it difficult to isolate the brain processes specific to deception. Farah et al. (2014, p. 125) cite a study by Gamer et al. as an example of this, in that Gamer et al. found showing participants pictures they had previously memorized resulted in activation in the same brain areas that are often implicated in studies of deception. Satel and Lilienfeld (2013, p. 79) cite an additional memory confound in that…

concentration of Triton-X to be 0.05%, so 1 mL of 0.5% was added to the final 10 mL matrix. Dr. Doolittle’s handout suggested that the optimal dithizone concentration was 50 μM in 10 mL, so 0.5 mL of 1μM dithizone was added to the matrix. 1 mL of solution was added to the matrix, along with 3 mL of water. In previous trials, 0.5 mL of buffer was added to solution (and water was added appropriately to get to 10 mL); however, this was later modified (see table below), as it was crucial to main a…

technology that could potentially grow into a huge part of our legal system and even now it is moving forward at a rapid pace and continuing to develop. We have made various discoveries and we have created ways to not only make our lives much easier but also to create reliable detections that could serve us in the courtroom. However, many argue that these advance technologies may not be as reliable as we would hope, which raises a big concern…

Brunetta and Guastalla (2000) gave a concept of free flight after their study on traffic network congestion which results in the ground holding policies that are quotient, on the other hand, Hormann (2001) focused on the cultural, organizational and behavioral elements of the aviation safety crew. In other research and examinations, Mathews and Kauzlarich (2000) centred on the ValuJet Flight 592 crash and performed a case study on the airline; Changa & Yang (2011) in their study were concerned…

A polygraph, or a lie detector, is a device used to detect duplicity by replicating a subjects inner reactions on a scroll of paper. A subjects reactions to a particular yes or no question would then be recorded on to one of the multiple graphs the polygraph produced. Many people feel as if a polygraph is the key to figuring out whether a person is either innocent or guilty when investigating crimes such as murders but, what they may not know is that a polygraph cannot fully be trusted. In the…

of deception”, the authors state their results show that fMRI is a reasonable tool for lie-detection in a courtroom (Kozel et al., 2004). Other authors agree with this generalization, however, there is highly contradicting evidence towards the fact that just activation alone of these areas does not mean you are lying. Further, does a lack of activation of these areas mean you are telling the…
