Two police officers assaulted by the same person and no charges brought? Ridiculously unbelievable. The show lost all credibility after that. I realize British police do not carry firearms, but as a former law enforcement officer in the USA, I suspect the British would be even more concerned about assault of their officers because of that fact. The show also demonstrates its ignorance through continually sending officer characters into the field alone without partners. These issues are so basic to law enforcement that it ruined the show for me. Which is unexpected due to the author's diligence concerning police procedures in her masterpiece Prime Suspect. Otherwise I think the actors are very good. The story lines are interesting too but get a little repetitive (secret rooms anyone?).
