Indeed it could happen here.

In churches, as the inflammatory introduction to this article implies?

I would say that the Canadian scenario where pastors are fined or sanctioned will happen long before U.S. agents sit undercover in churches.

By the time we have government agents getting set to arrest pastors, we will not longer live in a Republic but rather in some sort of totalitarian dictatorship. And if the government feels bold enough to do that, then there would have long since ceased to be effective opposition. Not unlike Nazi Germany in the 1930's.
