The JCC bomb threats paralyzed countless institutions, traumatized children who had to be evacuated from schools by a caller who warned that bloodshed would follow. While the caller didn't specifically mention anything anti-Semitic, it was reasonable to assume that the massive targeting of Jewish institutions for bomb and death threats was in intent anti-Semitic.
But the calls were coming from Israel. US and Israeli law enforcement teamed up and arrested a teenager with US-Israeli citizenship.
The picture being formed is closer to that of Adam Lanza, the Sandy Hook shooter, than what anyone expected. The suspect has unspecified medical problems that are probably psychological or developmental. He was home schooled. Israel has a universal draft, but the army rejected him. He reportedly attempted to grab the gun of one of the Israeli police officers who came to arrest him.
So what we were dealing with seemingly were malicious pranks by a nasty anti-social person. They might be anti-Semitic in nature. Israel does have some Neo-Nazis, though they're mostly Russian immigrants, but most likely it's just horrible people being horrible.
Jewish organizations were right to demand action. Having multiple schools being evacuated is traumatic to both students and staff. But they were wrong to allow the left to exploit the issue of anti-Semitism for partisan reasons. The left did not care about Jews. It did not care about anti-Semitism. It fosters anti-Semitism on campuses across the country. It was only temporarily seizing on the issue to attack President Trump. Once the suspects, a black leftist linked to the anti-Semitic pro-terrorist Intercept site, and apparently a Jewish teen, turned out not to fit their profile, they bailed.
Jewish organizations sacrificed their credibility by allowing the left to exploit them. And in the process they damaged the Jewish community as much as the two suspects did. If not more.
