The FBI knows without a doubt whether these were actual bombs built with the intent to hurt or kill. Or if they were just a hoax. Why have they not put that info out? Because they are partisan hacks, that’s why.
Or they are still investigating and will report when they are done. I have no idea if the FBI can be trusted on this. I do know that for Clinton and Trump they were corrupt to the core, with no objective professionals at all. But perhaps they can improve under Trump.
