Flags, 3G Hubs and Kirpans

     The news today is guaranteed to upset wives of those traveling to the Olympics.  A company contracted to provide security apparently was unable to find enough qualified Brits for the job.  The problem was solved by abusing an easily abused group - the military.  Uniformed personnel returning from duty in the Middle East had their leaves ("vacations" to you civilians) canceled to stand around London and put up with ill-tempered foreigners struggling with the overloaded London transit system.  For the soldiers, this will rank right up there with duty in Northern Ireland.  Be calm wives, your spouses will protected by angry military personnel with weapons.
     Security naturally is a major concern these days.  So here are some tips to avoid running afoul of the authorities.  First, discard the backpack you intended to fill with food, drink and telephoto lens for the events.  The backpack alone will place you in a separate, slower, queue (British for "line") to have the bag searched.  The lens, food and drink will be confiscated to mollify the soldiers.  An empty plastic bottle is permitted which can be filled with tepid water at the one or two water fountains to be found inside.  Second, Confederate flags are verboten.  The rules clearly state that flags of countries not participating in the Games are prohibited.  Also rules out any Free Syria flags.  Exceptions are made for England, Scotland and Wales, which are of course separate countries competing as Great Britain.  Third - and this is troubling - no "personal/private wireless access points and 3G hubs."  Could use some help here. How do you know if you have a 3G hub and how do you get rid of it?  What if you have a 4G hub?
     The presence of so much security definitely will deaden the conversation.  How do joke with a Sikh why he left home without his article of faith kirpan?
     Brits probably will not be disturbed by all these rules.  It is SOP for football (you know, soccer) fans.
