I currently attend a church on Sundays, and this church serves as a synagogue on other days of the week. Currently, there is a bit of security at the entrance, e.g. some security guards in uniform, but they are not police and do not appear to be armed. We get scanned by metal detectors before entering.
How could I bring up security concerns to this church, say, during coffee hour after the Sunday Service?
Basically, I wonder how prepared they are to counter something like a terrorist attack.
I don't want to offend anyone - how could I inquire about this politely?
