LONDON  -  Several dozen environmental activists scaled Britain's Parliament 
building Sunday to draw attention to climate change.

Greenpeace said 55 of its members were atop the building with yellow banners 
reading "Change the politics, save the climate."

The Metropolitan Police said officers were speaking to the protesters and 
there had been no arrests yet. The force said it thought there were 20 or 30 
people on the roof of Parliament's Westminster Hall.

I thought the Met had tightened security at Westmister after the last time 
( and the time before that, and the time before that, and ... ) ? Seemingly 
not.

It's not ecouraging that the Met don't seem to know exactly how many there 
are on the roof, though it could be argued they do and are simply trying to 
play down a highly embarrassing incident.
