Yep a video of the officer twatting the guy with a stick is pretty flimsy evidence for assult.....
I am not police bashing (no pun intended) but this does seem a bit much.

"After a thorough and careful review of the evidence, the CPS has decided that there is no realistic prospects of a conviction against the police officer in question for any offence arising from the matter investigated and that no charges should be brought against him."
