The SQ--a major Quebec police organization does the obvious--and I applaud it.  In addition to "reassessing" the way it conducts initial sexual assault investigations, it has decided that hundreds of previous cases will be reclassified as "unsolved" instead of "unfounded."

It's a step in the right direction. Merely semantics? Mas, non! 
It's important:   it eliminates the suggestion that complainants involved  made trivial or false or complaints.  I.e.: no judgement call.  Just not enough evidence to go forward, so...case remains "unsolved."  

Are advocacy groups satisfied?  No. One group's goal: encourage more women to come forward with complaints.  And this word change, they argue, won't do that.  Too bad: that's NOT the job of police forces.  That's the ADVOCATES' job.  

Getting back to semantics, however: police "dodged the bullet" so to speak.  "unsolved" presupposes that each of these files represents a case worth pursuing.  Better label: "No action--lack of evidence."
