I suspect (any advice on this much appreciated also) that an equivalent statement might be: “Bacteria play an important role in all infections.” – Is that statement tautological?
But would it be a tautology to say today that bacteria play a role in all infections?
There are two sentences in Gloria Laycock's position paper on defining crime science: (http://www.ucl.ac.uk/jdi/downloads/publications/crime_science_short_reports/launching_crime_science.pdf) where she writes: "The most significant and universal cause of crime is opportunity. If there were no opportunities there would be no crimes."
David Downes revealed the subtle tautology of that notion with this criticism of its very rationale “….the rate of delinquency in an area [is] the chief criterion for its social disorganisation - which in turn [is] held to account for the delinquency rate."
I'm currently writing a paper that I'm aiming at the journal: "Criminology" on the dangers of pseudo scholarship for crime science.

If there were no opportunities there would be no crimes."
Laycock’s statement is based on the first principle of the 10 principles of the theory of ‘crime settings’ by Felson and Clarke (1998): “Opportunities play a role in causing all crime.”
I am seeking advice from experts in philosophy as to whether this is a tautology.
I’ve discussed this with colleagues. One agrees with me that it is tautological – others argue it is not and is (a) a mere truism and (b) is so simplistic as to be meaningless. We all agreed on the truism and meaninglessness in that it says nought for the degree of effort and planning involved in different criminal events. For example, compare the offence of theft by finding (picking up £50 from the gutter and keeping it) with that of the bank heist caper (crack team breaking into a vault from rented shop next door using jack hammers and safe blowing experts, using inside info/inside men and lookouts etc. Both offences require opportunity of some kind.
Where on Earth is there a situation where there is zero opportunity for theft where a target for theft exists? And, therefore it follows, once you've stolen something you could no do so without having some kind of opportunity - could you?
Ok so its, arguably, simplistic but the point of this question is to ask whether the reasoning is tautological.
If it is not a tautology, then what is it about Laycock's two sentences that is not tautological according to the definition of tautology in logic: "A statement that is always true, especially a truth-functional expression that takes the value of true for all combinations of values of its components." (Collins English Dictionary).
I suspect (any advice on this much appreciated also) that an equivalent statement might be: “Bacteria play an important role in all infections.” – Is that statement tautological?
In terms of getting to the bottom of this question. Is it fair to say that the statement "bacteria play a role in all infection" is a tautology? And if it is - or if not - is Laycock's statement of the same kind?
Any advice greatly appreciated as I now know I need philosophical expertise.

Dear Kennethamy
Many thanks. You are right. I went onto another website called "ask a philospher" yesterday and received an excellent reply - as follows:
" Question: Is this statement a tautology: \"If there were no opportunities there would be no crimes\" ?
ANSWER
It depends on how strictly you want to define the word "tautology".
A) FORMAL: If you wanted to evaluate it this statement as a formal tautology you would have to rewrite it as a formal statement first. In the form
"IF NOT a THEN NOT b"
(a=opportunities, b=crimes)
it is not a tautology, but in the form
"IF NOT a THEN NOT (a AND b)"
(a=opportunities, b=actions, opportunities + actions=crimes)
it is a tautology, because no possible assignment of a and b makes the statement as a whole false.
B) RHETORICAL
Although, taken literally, it seems to verge on a tautology in a rhetorical sense, you could reasonably argue that it functions rhetorically as a stand-in for the substantive claim "preventing opportunities is the best way to prevent crimes". "
-----------------
I found this very helpful. And my reply to the philospher this morning (having thanked him for being so kind as to offer his free advice to me) was as follows:
"....I am extremely grateful for this - it puts what was little more than my own ill-defined gut instinct into something I can now describe with greater confidence and refinement.
In relation to your last sentence regarding the stand-in for a substantive claim: "preventing opportunities is the best way to prevent crimes". My next problem is with the very concept "opportunities" used in this way. The way I see it, if a building is vulnerable to burglary through having weak windows, no alarm, is hidden from the view of passers by and a vulnerable door lock fixing - then fixing these things does not strictly prevent "opportunities". Rather, it reduces the pool of potential thieves who will break into it - since now only determined, skilled and greater risk takers will pose a threat to the buildings contents. Opportunities have not been reduced (strictly speaking). What has been reduced is vulnerability. Because as soon as anyone overcomes any of the reinforced/improved characteristics of the building they took an advantage of the opportunity to overcome it (here is the tautology).
Am I being needlessly pedantic do you think? Any further advice greatly appreciated.However, I do not wish to burden you too much with these criminological concerns of mine as I verymuch appreciate the help already given."
---my email ends ---
As you can see my problem appears to be that I had to struggle with the issue of the tautology and then (as you point out) with the concept of what opprotunity means.
I think my mind is finally getting a grip on the issue.
Any further insights greatly appreciated. I will most certainly be making an acknowledgement to the very helpful and thoughtful generous souls on these websites in my paper.

The sentence, "All criminal actions are done only when there is an opportunity to do them" might express the statement:
All criminal actions are done only when it is possible for the criminal to do them.
In which case it is a tautology.
Or, the sentence might express the statement:
All criminal actions are done only when the circumstance present a fortunate juncture of circumstances for the criminal.
In which case it is not a tautology. It is false.

No it isn't. It's a truism, not a tautology.

No it isn't. It's true.
So when a person steals something in front of a lot of people so that he is sure to be caught, this presents an opportunity (a fortunate juncture of circumstances) for committing the crime?
