"Last Sunday, tens of thousands marched across the Sydney Harbour Bridge in
support of Gaza. But exactly how many people were there depends on whom you
ask.
Police put it at about 90,000. Organisers claimed up to 300,000. Other reports
and expert estimates landed somewhere in-between.
Why are these accounts so different and how hard is it, really, to estimate the
size of a crowd?"
