York Tunnel

Q59: Will an official announcement be made by the Toronto Police regarding the purpose of the tunnel at York University before the end of 2015?
Yes, suggesting that the tunnel had a criminal or terrorist purpose: 10%
Yes, suggesting that the tunnel had some other purpose: 15%
No announcement will be made: 75%
(In order for this question to resolve, the police need to announce that they have definite evidence that the tunnel either does or does not have a criminal or terrorist purpose.  There does not have to be absolute certainty.  The announcement does not have to specify what the precise purpose was, but it must be known to the police)

The Toronto Police recently announced the existence of a mysterious tunnel in a wooded area near York University.  There has been some speculation about why the tunnel was built.  The police have announced that they do not think that the tunnel was meant for any sort of criminal purpose, but this has not been ruled out.

I think that no explanation will be made for the tunnel.  Whoever constructed it could have already come forward, and have not done so.  The police seem to have exhausted all leads, and there is no particular reason to expect anything further to happen.

If the purpose of the tunnel is discovered, it is unlikely to be a criminal or terrorist purpose.  Although a criminal purpose would explain why the builders have not come forward, it seems less likely to begin with.  Also, a criminal builder is less likely to come forward in the future.
