Sweden arrested four terrorist suspects on the eve of 9/11. Their intended target was an old heating plant that had been converted to an arts center. Sweden has been focused on radicalized Muslim terrorism but with the advent of Anders Breivik (the Norwegian right wing terrorist/mass murderer), experts started to look out for similar groups. The Swedish government has released few details about the four suspects. The attack may have been related a Swedish cartoonist who in 2007 drew the prophet Mohammed.
According to Fox News, this wasn't the first attack by a Muslim suspect. In December, suicide bomber Taimour Abdulwahab blew himself up in downtown Stockholm among panicked Christmas shoppers, injuring two people.
The latest case from Sweden shows that terrorists are opportunists and will attack targets they perceive to be "soft". It also shows that attacks can be thwarted without resulting in the country becoming a police state.
