Hi,
Background: This is more like a strengthen question than an assumption question. The author has already provided the data required. All we have to do is defend author's take from being breached. We need to provide extra information which could to do so.
A)
Some of the people in police custody who had volunteered to undergo the polygraph test were not released without being charged : This is just the outcome of test. it is actually
weakening author's take. So, Move on.
B) Suspects who volunteer to undergo polygraph tests while in police custody for an alleged crime are more likely to be innocent of that crime : This does sound like
an extra pillar. If we can confirm that people who agree for polygraph test are actually innocent and there is already author's conclusion/
pillar that those who do not agree are more likely to be criminal, we are actually providing support and making author's conclusion/podium strong. Listener would be more likely to agree with author now.
C) The number of suspects released from police custody without being charged was greater than the number of suspects who volunteered to undergo a polygraph test: This will again weaken author's take.
D)
Some of the suspects who were not released from police custody were suspected of having committed more than one crime during the time period covered by the report : We dont know, nor do we care.
E) The city of egan has a higher crime rate than other cities of its size: I wouldnt say this even it were the last thing I had to say to support author. Author would just look at me and say WTF mate!!
