I disagree.Why does no-one ever mention Holland, or France, or Germany, or almost any other European country where all the police carry sidearms every day
Because influences, attitudes and trends of the British, tend to align more with the US than Europe. It's not just about the arming of the Police which needs to be compared.
Seeing armed police routinely patrolling our airports worries you?
Only in context of what a complete waste of time it is.
