When seconds count, help is a
long ways away:
Rowley said officers arrived on the scene 12 minutes after receiving the first call and the suspect was detained 10 minutes later, Rowley said.
I didn't see any officers getting injured in the video. As the comments say a 12 gauge would have worked a lot better than tasers. The British police are probably fortunate that the murderer didn't really know how to use one of those swords. I've seen demonstrations by those who train extensively with Japanese swords and within arms reach they are faster and deadlier than any firearm.
