But if you're talking about Agent Lang, that's right. He was suspected yesterday, but it wasn't enough for the majority to find him guilty. He was seemingly the first on the crime scene, he was uncooperative in his testimonies, and there was evidence in his back pocket with his fingerprints on it. However, that evidence in itself was suspicious, as it must have been planted on his person and thus could have been tampered with. As for the first two points, they seem to stem naturally from Agent Lang's personality, so it's hard to find him fully suspicious.

At least we know that they're definitely not working together. According to the badger's reports, Prosecutor Blackquill was one of the ones who voted for Agent Lang yesterday. So if Blackquill is guilty, than Lang must be innocent. And he may very well have been the one to frame Lang... but it is hard for me to believe in Blackquill stooping to something like that.
