I'm not a big fan of invading the Kingdom Hall like this but this particular protest was handled better than most I've seen.
As unreasonable as it is, the protesters message was discounted heavily by those in attendance, just based upon their appearance. JW's have great disdain for the world and anyone who appears to be part of it. They dismiss anyone who doesn't look like them, especially at the Kingdom Hall. If the protesters would have dressed in "meeting clothes" the JW audience would have been more likely to identify and sympathize with them because they appeared to be "one of them" rather than dismiss them as scary apostates.
What about the "attendant" who was waving his arms and blocking that woman from filming. What was he trying to prevent her camera from seeing? He was going above and beyond the call of duty which often happens when you give the merest amount of authority to someone with very little personal power of their own.
