We Must Learn from History

Yesterday I went to the Sydney Jewish Museum in Darlinghurst.

It was a confronting experience that begins with an incredible level of security. There's an intercom, locked security doors, a metal detector and guard to get past.

And that's just to get in!

It was all worth it though - as was the price of admission ($18)

However the extensive security made me wonder how society got to the point where a cultural museum is considered a potential high-risk target for attack.
