Samantha Lopez- Mary Pearcey (Jack the Ripper)

Family	Fallacy	Examples	Analysis
	Appeal to Ignorance	“It’s possible, but we do know this sample is likely to be a female sample. Maybe Jill the ripper?”	There is no evidence showing that it might be a girl. The only thing that shows is a guess from a detective stating that the person was wearing women’s clothing.
	Slippery Slope	“We take the DNA and add a number of genetic markers to the DNA. The genetic markers create a DNA profile. What we do is we take those genetic markers and effectively multiply, photocopy the very specific DNA fragments.”	This is showing how to get the results of the DNA. Ian is one of the people who wanted to find the DNA of Jack the Ripper. This shows how the DNA goes in order of how to find the results in the DNA test.
	Accident	“So it would be incredible to think that these blood stains either belonged to the Ripper himself or to one of the victims.”	This quote shows how the blood is the fact that someone killed someone but the part of who killed who is the question and it was the Jack the Ripper. This part is the no exception because it was just someone that it was.
Red Herring	Red Herring	“Well, we’re right in Mitre Square now.”	This section was talking about the DNA and it had nothing to do with the Mitre Square.
		“Yeah I think here you’ve got the real feel of the East End.”	This section was talking about how Jack the Ripper was killing his victims. Then it switched about the East End, which had no relevance to DNA.
	Straw Man	“Well I can just imagine this with some fog swirling, gaslights, flickering lights.”	This states how his beliefs about how people might be killed in a dark alley.
		“And turning the corner and seeing a body just lying in the corner.”	This is their belief that someone might be killed and where their body might turn up at.
Weak Analogy	Unrepresentative Sample	“It’s not a full profile, it’s a partial profile, which means it’s not sufficient to identity an individual and not good enough for forensic purposes but it is a partial profile. But, Jack the Ripper is not going to jail on this evidence.”	This was just a conclusion drawn up due to the lack of evidence found on the DNA letters. Meaning that there was not enough results found in the DNA test that could make it Jack the Ripper.
		“Ian’s partial profile was taken from the Openshaw letter, one of the most likely to have been sent by the Ripper.”	There are making the conclusion that it was Jack the Ripper because Ian was basing his conclusion of what they found of the detective.
False Cause	Cum Hoc	“A new DNA profiling case has been developed and the creator has travelled to London to take samples from letters believed to have been written by Jack himself.”	The two things that happened was the DNA case developing and the creator traveling which causes the samples of the letter of Jack the Ripper.
		“It was just this brief period of horrendous brutal murders that really captured the public gaze. The newspapers loved it, they gave it huge publicity. And when the name Jack the Ripper emerged it seemed to seal the whole thing. They had a name to focus on and a name to frighten people with. And of course he became the universal bogey man.”	The two things that happened was the belief of the brutal murders and then it was the public gaze. Then it was the name that gave people fright over the bogeyman.
