The corollary is that if states want to defeat guerillas or terrorists, they too need the support of the population. They need people to refuse to look the other way and to inform the police when someone is planning something. Unfortunately, the Australian police have just ensured that their Muslim community won't cooperate with them again:
About 2pm on Monday, December 15, Rebecca Kay took a phone call from NSW Police Counter-Terrorism.
The officer wondered if she could help police find an Islamic State flag. This was one of the demands of Man Haron Monis, the gunman holding 18 hostages at the Lindt cafe in Martin Place.
"And if they give him a flag he was going to exchange it for a hostage," says Ms Kay, a convert to Islam who has become a prominent community member in western Sydney.
Being a decent person, she was eager to help. But the Australian police abused that goodwill. They tapped all her phone calls (it would be fascinating to see what legal authority they had for that), then started raiding the people she called. The upshot? Further distrust, and an unwillingness to cooperate in future. The beneficiaries? The terrorists. Which really makes you wonder whose side the AFP are on...
