In the United Kingdom, police are required to conduct a complete investigation before determining whether a case was self-defense or anger after the event, according to Ian Kelcey, co-chair of the Law Societys criminal law committee.
The police have to go through the investigative process to show its been robust and send it on to the Crown Prosecution Service. The difficulty is how you do a robust investigation as well as a humane investigation for someone of that age, Kelcey told The Guardian. If someone is threatening you or attacking you with a screwdriver, its probably fair enough to grab a knife in self-defense. Its proportionate.

So you think people should be arrested BEFORE it's determined that a crime was committed? ---
