When we learned that the city was on the hook for the $18.3-million cost of last year's cyber attack, people were upset. In part because the actions (or inactions) of city hall staff voided Hamilton's insurance police but mostly because that huge sum was now going to be passed on to the taxpayers. As it is every time the city messes up. Which, unfortunately, has happened more than a few times (and in spectacular ways) in recent years.
