Dangerous Train Of Steel

Last week I wrote a post on dangerous shopping trolleys and just today came across this story from Cairns:

KEITH Denton risks having his foot amputated, three years after his ankle was squashed by shopping trolleys outside a suburban shopping centre...

...In July 2005, The Cairns Post reported on Mr Denton's injuries after he said he was pinned up against a wall by a "dangerous train of steel" of between 30 and 40 trolleys. At the time Centro had fobbed off Mr Denton's claims about the number of trolleys and said footage showed only eight.

The story doesn't describe in detail how the specific incident occured, but if trolleys were locked in corrals when not in actual use, surely it makes sense that workplace injuries due to shopping trolleys would drop.
