The problem is wider than the growth of extreme groups, it`s right across the board. Too many within our society are becoming more violent, more irresponsible, more agitated and less tolerant. There needs to be a big discussion, because those in political power repeatedly offer up excuse after meaningless excuse. They are reluctant to accept criticism and, following their convenient introduction of police and crime commissioners, have someone they can scapegoat and lay blame on. Theresa May (especially) and her cronies have a lot to answer for and at some time in the future their inadequacy will be clear for all to see.
People wealthy enough to live in private, select, gated groups of dwellings don`t have to worry so much. They can afford to pay out for private security to patrol their cosy neighbourhoods. Elsewhere, it`s quite probable that we shall, indeed, see a rise in vigilante groups and/or disreputable security firms, who will become less and less accountable.
I`m afraid that things will inevitably get worse before they get better. God help us if we have a major terrorist situation, especially outside of London, where most police resource is anchored. Policing is in crisis and many people are failing to get the type of service they deserve and expect. Dilute any large organisation and the quality of service dips; especially in a service which has seen huge cuts over many years.
Things are unlikely to get manifestly better until those in political power find the will to change, whether through self-analysis or as a result of massive public outrage. Police can`t do anymore, what you get with less, is less.
