You can look at the alternative in a place such as France. After the attack that took place in Paris, France, you had 5,000 French soldiers deployed to Jewish community institutions to safeguard them. I prefer to have some security infrastructure put in place that monitors the outside, that prevents unfettered access to the inside, and that has a security guard when things are acute, rather than having soldiers with automatic weapons posted at every single building.
I have to tell you that there are many in our community who feel that they should have soldiers posted outside community buildings, because they're scared without them there. It's a complicated thing.
