Security should either be total, or not done at all.
Then I guess there should be no security anywhere, since none of it is "total".
Security is rarely about providing 100% assurance nothing will happen. Its about making things difficult enough to deter most would-be trouble-makers, or convince them to find an easier target. This is balanced with what the patrons are willing to submit to, and what makes them comfortable.
Unless we are willing to tour the parks naked and submit to body cavity searches, security entering the parks will not be "complete".
Disney security does not provide 100% assurance nothing will happen, therefore it is not complete. But it does provide a measure of protection and deterance, and it is certainly more stringent than many other events in public venues I have attended since 9/11.
But I'm wondering what people think might happen to the parks if there was a terrorist attack. What might the short- and long-term impacts be in terms of people's perceptions, economics, and so on?
Yes, a good question. Short-term, we'd have much heavier security everywhere, and folks would tend to stay close to home, just like after 9/11. Gradually, things would "ease-up". If WDW were the target, obviosly the economic impact to Disney would be devastating, probably even moreso than the impact 9/11 had on the airlines. Whatever type of security was the victim of the breech would be beefed up at similar venues going forward, just as airline security became the focus after 9/11. Just some random thoughts...
BTW, it kind of bugs me for people to post about their perceptions of security flaws in such an open forum, but that's just me-
There's nothing being discussed here that wouldn't be known by anyone serious about causing trouble. When flaws are kept secret, all it does is keep the public from demanding the flaws be addressed.
