Inform the DOJ of this so they can stop wasting time, money & resources on drawn out investigations.
At the end of the day, it is illegal, but I agree that they should not be wasting time on this unless there is an additional angle, such as Hunter. The reason they need to be doing this is because we have to go tit for tat with the way an investigation was pushed over the Hillary emails and then back at Trump, and now they have to do the same for Biden. Nothing to do with whether it makes any sense.
Also this was a response to your question comparing it to a bank teller walking off with money.
