Another point: What about safety while in field circus? People can and do fall on stairs, but it is not really that common. I myself have seen maybe half a dozen situations where someone falls on stairs in my lifetime. Usually, they get back up within 10 minutes. Falls on ice are more common, but even those are usually wimpy affairs. I myself have fallen on ice, usually where there is a patch of unexpected ice or where a sticky spot unexpectedly appears. Those sticky spots are as dangerous as the slick spots. However, I am usually back up within 5 seconds with, at worst, a sore bottom.
What is more dangerous are the accidents on the highways. While going in field circus, people also need to watch out when crossing the street. I don't know how often someone got out of the car, in a hurry to start their time, and could have been hit with a car while crossing the street. To me, that hurts a bit more than a fall down stairs or on ice. They also need to know when householders are not in the mood, since there is nothing worse than being such an idiot that you go to a door where you know they don't want the message and someone with a gun or can of pepper spray shows up, or a dog is unleashed on them. Usually, these incidents can be avoided if the witlesses would only use common sense and not go to such calls.
Another neglected area in safety is going into houses with dangerous conditions. At least, at the a$$embly, railings are in good condition. Householders' places--well, that's another story. You grab a handrail, only to find that it is flimsy or can be pulled out of the ground with moderate force. Stairs are in bad condition--at a$$emblies, they are usually in fine shape. And I have seen halls where trip hazards are worse than at any a$$embly, and it is also badly lit. And halls where they are one blown light bulb away from being in pitch dark. Try going down the stairs when the lights go out or the bulb blows. How many witlesses make a practice of carrying a reliable flashlight in that eventuality? I never did while I was one, nor did I see anyone else do that.
And what about those idiots that are at the a$$embly when they are too sick? I have seen people that walked with great difficulty going into areas where it was not safe, and usually these are the ones to fall (or have heart attacks during the program). Wouldn't it be better to make a rule that, if you are too sick or laid up to walk safely, you should not go to these a$$emblies? What is the hardship of recording the program for later disbursement? These things can be uploaded onto the official site and available as streaming or MP3 files. That way, people most at risk of falling (and getting heart attacks or spreading tuberculosis) would not have to endure these issues.
