Those sizable numbers of attendees didn't understand the purpose of EMAS then
It is cheaper than the lawsuits resulting from the aircraft going over the side of the cliff.
Since it is a last ditch effort to keep the aircraft in the *safety zone* - the crew would have already used every effort to not use EMAS - sort of like the E-5 chain gear use to be.

Here is a nice fact sheet on EMAS

Also, this link is a good article which covers the basic of field arrestment systems with an airline flavor! E-5 is described near the end.

They really were like LARGE piece(s) of chain strewn across the overruns in case you missed the regular arresting gear (BAK-XX, E28 style). They started removing them some time ago for some reason - I don't know why.
