Is the ADL squandering its credibility?

From the Volokh Conspiracy…

Has There Been a Surge of Anti-Semitism Under and Because of Trump?

Those who wish to blame Trump have an ace in the hole, an Anti-Defamation League study that purports to show an almost 60 percent increase in anti-Semitic incidents between 2016 and 2017, which is implicitly blamed on Trump. This study has been cited on over and over in response to Pittsburgh.

There are several problems with relying on this study for Trump-bashing, however. The first is that the study includes 193 incidents of bomb threats to Jewish institutions as anti-Semitic incidents, even though by the time the ADL published the study, it had been conclusively shown that the two perpetrators of the bomb threats were not motivated by anti-Semitism. One can only guess why the ADL chose to inflate its statistics in this way, but none of the explanations speak well of it.
