I don't feel the need for a camera any more than I feel the need for a helmet - I'd rather avoid the situations that they are supposedly 'designed' for.
Am unclear as to what "they" refers to. I am not sure how one can avoid other people's lapses of concentration or acts of unwarranted aggression (eg punishment passes). So at times the idea of filming is very appealing.
