Why is it not practical? Near as I can tell, three reasons are given for police.
1. Crime prevention. But there are relatively few cases where the police actually intervene in a crime in progress.
2. Crime deterrent. I'm not sure how well this works. One would think that if police presence were an effective deterrent to crime, crime would be lowest where police presence is heaviest. But in reality it seems as if just about the opposite case prevails.
3. Catching criminals. This is what the police seem to do most effectively. My suggestion was that with no police or few police, we would have to develop a much better system of citizen's arrest.
You didn't make a suggestion because you didn't explain yourself. All you asked was whether getting rid of the police would "make it easier to organize with the neighbours."
Anyway, how is that not swapping out one force for another? Trained police officers and emergency responders for an untrained group that would have to develop (in other words become trained) to do the same job?
Taking something established, which can always be improved upon by the way, to replace it with something unestablished where people have learn as they go and develop the skills necessary to be effective at doing the job is highly impractical.
You will never upset me, don't you go worrying about that now.Sorry if I upset you by pointing out that argument by anecdote isn't a very good method.
