Dudes — there is a thing as being too careful.
As seen on Slashdot: David Mery offers The Guardian a story about his experience of being arrested in The Underground for apparently being too much of a geek, all in the name of anti-terrorist security.
This Reuters story was written while the police were detaining me in Southwark tube station and the bomb squad was checking my rucksack. When they were through, the two explosive specialists walked out of the tube station smiling and commenting: “Nice laptop.” The officers offered apologies on behalf of the Metropolitan police. Then they arrested me.
