As a kid I lived near the cats-eye factory in Yorkshire and used to collect reject cats-eyes as catapult ammunition. They went vast distances and were handy for knocking out street lights. Wouldn't dream of doing so now and no doubt I'd be the first to complain if some kid knocked out the lights in my street. However, I never harassed the neighbours, never bullied anyone and certainly wouldn't pick on anyone mentally or physically disabled. I think it helped knowing that you'd be in big trouble at home if caught whilst up to no good.
