Select Layer by Name (with or without objects)?

I appropriated a script from this thread​ (thank you, pixxxel schubser).

It works as long as "myLayer" contains object(s) (even if they are locked and hidden). How can I change it to select the layer whether it has artwork or not?

I tried setting "hasSelectedArtwork" to "false", but no cigar.

var aDoc = app.activeDocument;  
aDoc.selection = null;  
try {  
    // be sure that top level layer with name "FINGERPRINT" with sublayer with name "Fingerprints" exists  
    var myLayer = aDoc.layers.getByName('FINGERPRINT').layers.getByName('Fingerprints');  
    myLayer.hasSelectedArtwork = true;  
    }  
catch (e) {  
    alert("the layer doesn't exist");  
    // do whatever you want  
    }  

Here's a sample file. The script will select "Fingerprints" layer unless the layer is empty.
