My wife and already routinely spoke Spanish when we were in questionable neighborhoods. Now, it's all we speak outside the house. And we include the annoying fake accent (full disclosure: hers is solid; mine is borderline offensive depending what border you're standing on).
I don't know what public face they'll give this, but local security is on edge. Tighter than I've ever seen them. And frankly, we are too.
Pre-post edit: deleted paranoid conspiracy speculations. I mean, I have been drinking since brunch.
