How did Moore end the statement?
First, let's look at the statement and then consider his question.
The question is, "isn't it strange that after 40 years of constant investigation, people have waited to four weeks prior to the general election to bring their complaints?"
This is a yes or no question.
For some, it will be "yes, this is strange", while others will say, "no, this is not strange."
They may disagree on yes or no, for the very same reason.
"yes, it is strange" as to why the victim waited 40 years to make the statement public.
But if the allegation is true: he took off the clothes of a 14 year old girl and sexually molested her, would it matter if the timing is strange?
Would it matter if the motive was to destroy him politically?
Would it matter if the motive was to harm Donald Trump, Republicans, or even the entire country?
Whether it is strange or not, the question is, "Did you do it?"
To this, he has had many opportunities to plainly deny the allegation of sexual molestation.
Instead, he not only avoids the simple reliable denial, but he seeks to attack motive.
The motive may be illicit, or it may be even vengefully made, but it does not change the allegation nor Moore's inability to deny it.
What happens from here is this:
The more he avoids the allegation and instead turns to attacking media, political rivalries and the motive of the accuser, the more the untrained public will realize:
he is not truthful.
Had he said, "I did not molest ______. I did not remove her clothing, nor have her touch me", the story would not have gotten as popular as it has been.
This is the issue with reliable denials in media:
They are boring and do not "sell newspapers", including in the internet world.
Sean Hannity was even handed with Moore and even fed him wording to use, yet, in the "free editing process"; that is, when one is speaking for oneself, Roy Moore was incapable of denying the allegation.
Here he has signaled that he has knowledge that something, in deed, did take place.
This is a change from his earlier statements.
At a certain point, he may read analysis (or have it reported to him) and issue a reliable denial, but given the amount of free editing time afforded him, it should not be considered reliable.
We have an expression in the world of criminal analysis:
If the subject can't say he didn't do it, we are not permitted to say it for him.
