How does this strike you?

“We turned to see the police hitting people. A whole line of them lashing out indiscriminately again and again. Two officers close to me who had “Police Medic” written on their back were walking up and down behind the line of their colleagues, protected from direct assault, reaching over and thrashing with the most gusto of all.” – (source)

UPDATE – Oops. I thought I was linking to the original earlier, but the original by amjamjazz can in fact be found here.

Via comments in the original photo thread; video footage of more madcap medics in action (relevant clip at about 2.05 onwards).
