Cross-Pond Solidarity
Yank viewpoint - it's bad enough when the politicians manufacture the crisis in order to gain power from a frightened populace, since it is at least possible to see the falsity of the situation. Here, (and no finger pointing coming from me, since our own set of dipsticks has allowed an equally bad, if not worse, situation to develop over here), they have allowed a *real* crisis to take place. The situation is so bad that a verifiable proof of legal residency is now a reasonable response. Oy! (Can of worms caused by the word 'verifiable' in the preceeding sentence is noted and purposefully avoided).
{IT angle - or at least, tech angle - as for the actual radiation... are gamma rays used in common devices which are used or encountered by the general public? If not, then I admit to a lot of uncertainty regarding safe levels. Physicists, please respond. Is all radiation created equal? That is, is a dosage of X intensity for Y duration of X-rays equally as hazardous as the same dose in gamma rays or neutrons? I don't mind causing illegals discomfort (say, to the level of tear gas etc.) during detection, but permanent damage goes too far for me.}
BTW, is the gamma ray device so much better than heat sensors? If it is, then full speed ahead (oh, and don't forget to arrest the driver and impound the truck - sell it at auction to reimburse the government for a small portion of the expenses and sentence the driver to street cleaning or other community service in neighborhoods known to be illegal sanctuaries).
{Paris Hilton angle - see if irradiating her with Gamma particles will turn her into the She-Hulk - that's hot!}
