I hope so..They would love to do a double header I am sure..
Europe I am certain will be on full alert,too...
The thing about "leaving a package" is that it is so easy to accomplish..
It also appears that worldwide sympathy and anger with this attack is going to be HUGE. Most people around the world know the history of the London Blitz in WWII and the IRA bombings, and are horrified to see Londoners going through this again at the hands of Islamofascist freaks. It also appears to be very stupid and hamhanded to pull a deadly attack just days after Live 8, when millions came together around the world to support efforts to fight poverty in Africa. The terrorists have really blown it this time IMO.
God save the Queen and Great Britain!
