Any police officer who refuses to walk the beat alone must be sacked. No sympathy. I walk these streets alone, without the benefit of kevlar bullet-proof vest and a communication system that includes an 'urgent assistance required' alarm button and without the benefit of the full rigour of the law being applied to anyone who assaults me. If a well-armoured and protected plod isn't safe on the streets, then the streets aren't safe for anyone - and we should sack the Commissioner.
And if 'modern' plods are nervous, it's about time they remembered two things well understood by old-time plods;
1. Being polite and respectful to the public will make them your allies
2. Law-abiding middle class blokes are most likely to come to your assistance if you're in trouble - so lay off trying to criminalise them by the overzealous imposition of noddy-offence penalties
In London, the greatest volume of complaints against the Met are over the rudeness and arrogance of individual officers. Patrolling alone will allow these confused individuals to remember who pays their wage, and why.
