Phil Booth has published a comprehensive write up of the "Mistaken Identity" meeting held at the London School of Economics on Wednesday, on his infinite ideas machine blog which has been picked up by the widely read superblog boingboing.net
The issues and concerns about the Draft ID Card Bill and the proposed National Identity Register biometric database were aired by distinguished speakers, including the frontbench opposition spokesmen from 3 major political parties, who thought it important enough to come to the meeting, despite the "purple flour" security incident in the House of Commons, just prior to the meeting.
If the "purple flour" had actually been a biological weapon, not only would have several Members of Parliament been infected, but the audience opposed to the Draft ID Card Bill would also have been at risk, along with the rest of the population of London. Those MPs really should not have evacuated the House of Commons Chamber so soon. Analysis of chemical wepons can be very quick, but this is not so with biological ones, despite lots of research into cheap Biosensors, which are likely to produce lots of false alarms.
