The police definatly do not shoot to wound, but I don’t think they shoot to kill either.
I think they shoot to neutralise the threat as quickly and effectively as possible. If you die you die and you live if you are lucky.
If there intent was to kill, after gunning down lee rigbys killers they would have walked over and put one in their heads.
But they didn’t they instead started first aid with the intent of saving them.
When visiting a friend in hospital last year there was someone on the ward who had two police officers with him the whole time. I asked him why, he said he had been shot eight times. I said is that what the police were here for, to protect him from who ever shot him. He said no it was the police who shot him. And when I asked why he just said gun crime.
