This is what was once called the "human interest" story.  Whatever it's called now (by some: "lefty sob-story") the purpose remains the same: pluck the heart-strings and encourage sympathy for our own version of "huddled masses yearning to breathe free." All that's missing here is a reference to Canada as terminus for the fabled "underground railroad." However, no, there is no comparison possible to the mid-19th century phenomenon, during which an escapee--as they called him then--could earn his keep by mucking out barns and feeding the livestock. Another difference: it took  decades for 30,000-40,000 blacks to arrive here.  It took just one year (2008) for the same number of asylum-seekers to make their claim. 

We can't stop this.  

What we can do:
1. Quickly send them back--the cost will be less than to keep them here. 
2. Spread the word, Trump-style: i.e.: social media--"border-jumpers are sent back."
3. Lower the annual refugee intake to compensate for these border-jumpers.
