So what evidence is there that politics were involved besides the article's speculation that they were targeted because of their support of the anti-union law?
Also, where was Scott Walker during all of this? You'd think he'd make a fuss about it, if it actually happened (I doubt it).
EDIT: Also, those "targeted" by the investigations say they don't trust police now. Welcome to 2010s America, guys.
The particulars will be rather difficult to prove given the nature of a John Doe investigation. However, in this case, the prosecutor, Chisholm spent years trying to investigate Walker for some nebulous undefined crime and multiple judges have ruled there is no case. The conservative group here (Wisconsin Club for Growth) actually sued in federal court to have the records of the investigation (which was done against them) publicly released.
Whether there was a battering ram or not, I don't know if we'll ever know, but that Chisholm directed several pre-dawn raids on the homes of high profile conservative activists in the Milwaukee area is pretty well known. That the investigation hasn't turned up anything is also well known, as are Chisholm's political views. Given these circumstances, there ought, at the bare minimum, to be an investigation into Chisholm's office for malicious prosecution.
