Real life isn't an episode of Law and Order, where everything is wrapped up with a neat bow in 45 min or less.  Investigations take time.  It took about 2 years for Nixon's resignation and Bill Clinton's impeachment took a similar amount of time, from the time the investigations began.  Be patient, indictments may still be forthcoming, depending on the Mueller investigations and whether or not he goes public with his findings.  Also, do you honestly expect our current DOJ to actually push for indictments of the President's own kid?
