I was wondering something similar. Often times recent news tends to overshadow search results.
Let me give a practical example. Grand Jury. proceedings have undergone serious reform since the 70s. In some states a target can demand to appear before the Grand Jury. In some states a No Bill precludes the State from representing the case. In others there must be clear new evidence before a case can be represented. I know one state has a three striges rules for GJ proceedings ( sorry don't remember which).
The day before the Michael Brown shooting, a search on Grand Jury Missouri would have found several articles on the specific laws to Grand Jury proceedings in Missouri.
The day the DA announced he would present the case to a Grand Jury, the same search gets hundreds of articles on news story about Michael Brown and Grand Jury proceedings, but it becomes impossible to find those same scholarly articles about the peculiarity of Missouri Grand Jury proceedings. Not even the relevant statutes from the state website.
What can be done to mitigate this effect?
