I have to say that a outburst in the Kingdom Hall or whatever, shouldn't rattle the JW, ESPECIALLY in the inner city/ghetto. I was raised in the inner city and I remember cases where nutcases came in the hall. Some were JW, while others came off the street and we're firmly escorted off property. I remember one of my childhood friends talking about a incident with a homeless, crazy man coming in the hall and making a disturbance. He said his father, a elder, and a few other brothers got physical with the guy. They got in a few punches right in the Hall. Therefore, I don't think JW will assume a "apostate" will be the ones guaranteed to disrupt a service. Their meetings are open to the PUBLIC you know. They can just make their Memorial a private event with ONLY invited guests by their invitation. That would cut down on the crazies coming in. I know they do a decent job of security at the halls. At least the ones where I went to. They always had the big brother sit by the door or at the desk with the CCTVs. Hey but if we want to take it to the extreme, hypothetically speaking, a person could come in the hall dressed up and leave a bag with a bomb and walk out. I heard of bomb threat at the old Woodland Hills assembly hall, which was over 13 years ago. Everybody had to quietly evacuate that day. I still don't know who was behind it. Maybe a EXJW. Anyways, it's a crazy world with crazy people and crazy religions.
