Yes but terrorists never blockaded the fuel pumps. Most people are sheep and will panic and the slighest thing out of the norm.
The intelligence of a crowd is the IQ of it's stupidest member divided by two.
Considering that the UK has people who read the Daily Star this makes the intelligence of a big group of people very low indeed..
Also, I wonder if we can get the media classified as a terrorist group. They've cumulatively caused more panic, problems and terror over the last 20 years than any terrorist group has.
