The British police arent meant to be security forces.The problem imo is the weak criminal justice system,which should serve & protect the citizens,but it has in many ways disconnected itself from that role.As TG said there is far too much emphasis put on the human rights of the offender these days.We have had a social experiment taking place since the 60,s in justice,education and many other areas and it has led us to the point we are now.
Its time we had a govt. which admitted that the experiment has failed and announces that we are returning to punishment fitting the crime,life means life and possibly even the return of the death penalty,although Im still uncomfortable with that personally.
There always has been and always will be nutters who will murder innocent people,but logic tells me that if there is a really strong deterrent,the number of this type of incident will be reduced. Its possible to murder someone these days and serve less than 10 years in prison.
A workmate of mine did 3 years for GBH a while back and he said prison is not really a punishment these days.The worst part of it is that it gets boring after a while and you cant go down the pub,but theres nothing to deter anyone from returning to a life of crime.
By all means try to discover why people do these things,so that it may be possible to steer people away from doing it in future.But once an indiviual has cold bloodedly murdered someone they should never taste freedom again imo.
This is all purely hypothetical of course becaue even if we have a govt. which wants to go back down this route,the EU wouldnt let them.
I grew up in a place where all police carried firearms all the time,my Dad was one of them in his younger days.In the circumstances it really was necessary for them to do so but it didnt stop police officers getting murdered. There were hundreds of them murdered during that time. Often in their own homes or cars,where they had their firearm to hand,but a surprise attackby an armed gunman is usually over within 2 or seconds,so not much time to react unfortunately.
