18. Section 4: Your Selection

19. Reflection: Kah Xuan
Through the entire course, I have learnt many new skills regarding laboratory works. I was exposed to more forms of experiments and found out that during the experiments, much skills learnt in lessons were applicable. However, sometimes, we faced difficulty when the task only required us to look for matching evidences. We found it hard to describe and compare, since there were only guidance in words but not actual examples for us to follow. I also feel that to the solve case, I will have to be very clear of what is going on. Hence, we attempted to construct a timeline to point out specific events that happened. Unfortunately, even though we deduced the murderer, we were unable to find out who were to ones who made the anonymous calls and what were their motives. We also had to be extremely attentive during the question asking session as we had to look for contradicting statements made by the respective suspects and witnesses.

20. Reflection: Yu Hao
I feel that this IDS lesson given to us is very fruitful as we get to do many hands-on laboratory work that we will not have a chance to do during our normal laboratory lessons in class. Furthermore, listening and watching forensic scientists in work is totally different when I myself tried to do it. In this whole crime solving, I finally understand that I am not very suitable to be in forensic science. Since young, I have aspired to be a forensic scientist but after this 4 lessons of work, I find that I am not observant enough and I cannot link the evidence up properly. Also, I could not chain up my thoughts when it comes to brainstorming. But I think that all these need experience and it all takes time. After all the lab work, I realized the importance of the recording and reliability of evidence. Just like the fingerprinting, we need a minimum of at least 8 matches before we can determine whose fingerprint is it. Last but not least, I enjoyed the forensic lesson provided and would hope that I can join next year too!

21. Reflection: Chuan Xin
The part of the entire course that has taught me the most was not the experiments, but instead the questioning sessions. Short as they were in comparison to the laboratory sessions, it was by far the most important. In the short questioning sessions that we had, I learnt that the phrasing of the question is very hard, and that it has to be very precise, or a false answer can be given very easily. This questioning session really pressed the brain hard to think of the right question to ask too. Also, the questioning session helped me learn that there is a lot of trial and error in questioning a suspect, but a lot of it boils down to listening skills. We had to try a lot of times before we could identify the right person to ask questions, and also that was only due to hints that was given by Mr Bill. Also, identifying a suspect is hard, since the most likely suspect will be the one who does not give the answer, and we have to look at a person seemingly unrelated to the whole thing, someone like Janet and Helen Perry, totally unnoticed till the hint was given. This reflects a lot about our listening skills. I have also learnt that I should dare to speak up. On day 1, when a person asked the question about Janet Perry, I already had the thought to question her since she was sober. However, I was too shy to go up to the microphone to ask my question. Otherwise, the case could have been cracked on the first day itself. However, this is now something that I have to improve on, and now I know it.

22. Reflection: Sheng Xiang
After this IDS course, I had learnt more about the different method to crack a case, all the different laboratory work. For example, before this IDS sabbatical, I had only few knowledge about how those forensic scientists make use of the evidence to crack the case. However, after all those laboratory work, I had learnt more about the different methods, such as the matching of fingerprints, bite marks, foot print, and even lip stick. I had also learnt all those different things to look out for when matching evidence, for example the whorls, arch, composite fingerprints.
Other than the laboratory work, I had also known how to ask good questions that will aid us in solving the case. We had to examine the evidence as detailed as possible, and by looking at the possible contradictions and loopholes, we could ask the suspect. However, the suspect’s statement might not be necessarily true, thus we had to confirm it with other suspects’ statement to reconfirm it. With the help of the suspect’s statement and the evidence at the crime scene, it will bring us closer to solving the case.
