Easy fake terrorism

You can see how absurdly easy it is to create a fake 'al-Qaeda' terrorist attack. Take one petty criminal from Madrid of plausible ethnicity and pay him some money to hang out with some people who the authorities can associate with al-Qaeda. After the bomb attack, either plant a bag of unexploded bombs or find a real dud bag and, while it is in the police station, put a phone and a phone card from the shop of the petty criminal in the bag. The criminal is instantly turned into Lee Harvey Oswald, and the bombing attack is instantly turned into an act of Islamic fundamentalist terrorism.
