Memo to reporter and editor: 

I recognize that the workload may be excessive.  I understand that you and others work under severe time constraints.  However, readers deserve better than this: "...whether Salvadorans will follow in their footsteps is, for now, an scary unknown..."

1. Delete the adjective "scary" (or any other adjective). I don't disagree that the future actions of Salvadorans are unknown, simply because they haven't happened yet.  Nobody know what they will do--if anything.  Delete redundant, "for now" 

Actions of Salvadorians are only "scary" if...
2. Salvadorians are, as a group, are dangerous.
3. A high number of them attempt to enter Canada within a very short time (possible, but again, unknown.)

If tens of thousands attempt to enter Canada over the span of a year or so, that would be, arguably, not scary to most of us.  Canada brought in 23,000 Syrians in a matter of months.
