1. No charges against Walker. The material released Wednesday was nearly four years old and part of an investigation that ended with no charges against the governor. The 27,000 pages of emails consisted largely of volumes of old news, office gossip, political chatter, and unproved allegations. 
2. Nothing new.  Nothing in the new batch of emails incriminates Walker in any way. If there was evidence of criminal activity, prosecutors would have filed charges. Instead, they shut down that probe without charges against the governor. 
3. No link. The emails that supposedly "link" Walker to the "secret" email system don't.  In one email, Cindy Archer mentions that she uses a non-public email to communicate with Walker. The "secret system" turns out to be... a private email account. Despite the breathless headline, it does not show that Walker knew of the secret router system that Kelly Rindfleisch used to conduct campaign work for others. Archer's house was subsequently raided. Neither Archer nor Walker were charged.  In another email cited by the paper, Walker tells a staffer "No more laptops." This is not evidence he knew of a  "secret" system.... it is evidence that he wanted no political activity by county staffers. As our Savvy Pundit notes, the email shows "Walker firmly telling staff that any sort of mixing of campaign activity with his office work was unacceptable – no excuses, no technological end-arounds, no more."
4. Court of public opinion... not of law.  The prosecutors who released these emails could not convict Walker in a court of law, so they are resorting to a media trial in the court of public opinion. 
5. Prosecutorial bias. In both John Doe I and John Doe II Prosecutors targeted only Republicans, not Democrats. In 2012, Media Trackers uncovered 43 Scott Walker recall signers in the Milwaukee County District Attorneys office. The Chief Investigator of the John Doe, David Budde, was even caught posting the union blue fist and a "Recall Walker" sign in his yard while he was working on the probe. 
6. Prosecutorial abuse. The "secret" investigation included the jailing of two innocent businessmen (who were never charged with any wrongdoing) by the Doe prosecutors, as well as numerous leaks from the supposedly "secret" proceedings.
7. Partisan frenzy. The Democratic Party and their liberal allies are all-in on the John Doe. For weeks, Democrats have been raising money off the investigation - insinuating crimes and corruption. The DNC put out a statement less than an hour after the documents were released saying they raise serious questions about illegal activity. A Hillary Clinton aligned super PAC was in town on Wednesday to pour over the emails in hopes of finding the right narrative to knock off a potential 2016 challenger. For Democrats, the John Doe is the political strategy.
8. Media overkill. The press is investing a huge amount of manpower on this story, so they have to hype the smallest item to justify the expenditure of resources. The Milwaukee Journal Sentinel invested 10 reporters to the Doe emails on Wednesday. The Wisconsin State Journal live-blogged their findings. Reporters from all over the country tweeted throughout the day. And what did they come up with? Some loose insinuations that prosecutors couldn't prove, a lot of office gossip, and even inane details about a house smelling like cat pee.
9. An endless investigation... but no crime. The investigation is continuing, but the judge in the case has already ruled that there is no evidence that any crime was committed. The John Doe II probe allegedly centers on charges that Scott Walker’s re-election campaign and dozens of conservative nonprofit groups known as 501(c)(4)s may have illegally coordinated their efforts during the 2012 recall campaign. But in quashing numerous subpoenas, Judge Gregory A. Peterson, the judge presiding over the Doe, has ruled that  the prosecutors had not shown "probable cause that the moving parties committed any violations of the campaign finance laws." What the targets were accused of doing, the judge said, was in fact, protected free speech.
