I've heard some pushback about the reasoning behind Stone's arrest, calling it suspicious that CNN was "tipped off" and he was "leg go and didn't even have to make bail." Is it common for the news to catch arrests like this, or was CNN tipped off? If CNN was tipped off, what does FBI have to gain from publication of the arrest when Barr was appointed Attorney General?

I can't find clarification that Stone was released without paying bail. I imagine he could easily afford it, but is there a reason why he would be released without paying?
