Car bombers need
1. nails (which can be obtained easily if they know someone in the roofing business);
2. propane canisters (which can be obtained from someone working at a convenience store);
3. cell phones (which can be obtained at a convenience store);
4. gasoline (which can be otained at some convenience stores);
5. a car or truck (which can be borrowed if you know the "right" person at a car rental place.)
However, they can shape liberal party politics to their liking, which is potentially dangerous to me and the nation. Therefore, liberals are the terrorist's only real weapon.
