Maybe the Security people like you, Diana.

We're missing something here. Beckham will come to LHR from the Irish Republic, another EU member country, and not from the U.S. He won't have to clear Immigration & Customs. Any delay he encounters will entail picking up his checked luggage, checking in for his connecting flight and going thru Security. Barring unforeseen circumstances, 3-hours should be more than enough time, even if he does have to change Terminals.
