Checking the claims: Were there really over 2,000 policemen stationed outside the Capitol Power Plant yesterday?

"Thousands" Allegedly Converge in DC for Capitol Climate Action Against Dirty Coal

Since 2 pm, over 2,000 activists have blockaded the three main gates to the Capitol Power Plant. The rather larger police turnout is impressive; clad in their best stocking caps, they dot the chain fence like lamp-posts, taking in the gregarious march with a bit of interest and fascination. No attempt at any arrests have been made. The crowd is controlled and peaceful; there is a festive atmosphere, young and old, all bundled up and dancing to keep warm on this crystal clear but chilly afternoon.
