Dreadful: dreadful. Nothing else but.
We need a multi-party approach, its just politicking to blame the current government alone - and absolutely helps no one at all.
I would have thought tasering was enough ,kicking gin the head wasn't necessary: and yes on the R4 6pm news it was state the attacker had a history of violence and serious MH problems. (Thats not a get out, btw, it was mentioned by WWM upthread, "it's official"). Terroist groups, if this is a group plan, will choose someone who can be easily persuaded to take the role.
BTW, a group has claimed responsibility: "Iran-linked militant group claims responsibility for Golders Green terror attack" from the I newspaper: it was on the BBC 4 new too, and report
That doesn't mean to say they did do it, but its needs to be investigated, as it could be the source of a planning group, or it could be another sick lone wolf.
