Once again,
@Joe Fan Fan takes a small story with a kernel of truth to it and draws wildly unsubstantiated conclusions.
Yes, there is a problem with the Wayne County (Detroit) recounts. According to
this article in the Detroit News (the city's conservative paper), the problem is that there are discrepancies between the number of votes in the sign-in books and the number of votes on the machines. The discrepancies ranged from 1 to 5 votes per precinct.
The discrepancies are attributed to super-old voting machines, which jam frequently. This would seem to indicate under-votes (to the Republicans' favor), but the article indicates the possibility that some votes may have been resubmitted after jamming, resulting in over-votes (to the Democrats' favor). I looked briefly, but haven't been able to find any indication of which direction the discrepancies were in. The only mention I came across referenced a single precinct, which had an under-vote. I'm sure more about this will come out soon.
Regardless, if the discrepancies can't be reconciled, the votes will not get "tossed". Under Michigan law, there will just be no recount and the original results will stand.
The evidence that has come out so far points to a faulty system, implemented incompetently. This story is definitely worth following, and it may well reveal fraud. But it hasn't yet.
