No physical evidence is ever provided without some sort of testimony as to its provenance. The legal system was already equipped for this, in theory. The bigger problem recently has been that when someone is willing to lie about their faked evidence, it's harder to detect and impeach the testimony introducing that evidence. So it's a problem, but not a structural one. The existing structures are already designed to handle forged evidence. The issue is that it's more expensive and technically difficult for parties to audit evidence in search of that forgery.
