From the NY Post article:
It's high noon for the high holidays.
Fearing jihadists will attack synagogues during Rosh Hashanah and Yom Kippur, a group of badass rabbis has developed a program to turn your average shul-goer into a lean, mean fighting machine.
The group, which calls itself the International Security Coalition of Clergy, was founded by Rabbi Gary Moscowitz, who boasts a black belt in karate, teaches martial arts and was an NYPD cop for nine years.
He's teaching others basic and advanced fighting moves -- how to take down a terrorist by the neck, how to use a table as cover from gunfire and how to execute a nifty running somersault while drawing a gun -- that he says can be used by Jews if they're attacked by terrorists during prayer. ...
Read the rest here. I do note that the rabbi in the video appears to have poor trigger finger discipline. Perhaps he was an NYPD cop when they were still issued revolvers, and developed that unsafe habit (as did many other NYPD cops) with that (relatively) heavy trigger pull weapon. In fact, I believe one of the reasons Glock developed the NY-1 and later the even heaver NY-2 triggers for the Glock 19s that NYPD issues was due to the poor trigger finger discipline of the cops who carried revolvers. The NY-1 and NY-2 triggers also make the Glock trigger feel more "revolver like".
