The thing about the law is that it protects some people and not others. It very much depends on what side of it you stand on. So whether or not an informant that was looking into foreign governments attempts to manipulate the 2016 election is a good or a bad thing very much depends on whether or not you think foreign governments manipulating the US election was a good or a bad thing.

I don't like speculating, and we'll know a lot more in a couple of months, but it does seem weird that the Trump camp has such extreme lapses of memory when it comes to their russian ties, and only seems to remember the facts after they have been uncovered by outside agents.
