"get" or "is" regarding the future
Solution 1:
I offered my correction to Tim because, in the question in question, the implication in "if guns get outlawed..." is that some external agency (malign in this case) would be required for change to be effected. "If guns are outlawed..." seems much more value-neutral to me. I accept that the difference is subtle, but I believe it's there -my ear and kiamaluno's graph say as much to me.
Solution 2:
Either one is fine. Functionally there is no difference between the two.
