You sound like you haven’t the foggiest idea what the job is actually like.The problem is that coppers don't exist anymore. Police forces are so undermanned that they pretty much take on anyone who's prepared to apply. That's why we see young 9 stone weaklings patrolling our streets while the more experienced lazy bastards who 'know the game' drive round chasing speeding cars, sitting on their fat arses in 'specialist' cyberspace teams, and posing on TV reality shows.
The days of the public being protected by the police are long gone. Criminal society has been aware of that for years.
Don't expect things to improve.
The police lost most public respect during the miner's strike 40 years ago. They've done nothing to improve their reputation and in many areas of their work are even worse.
The term "never trust a copper" has never been more appropriate than nowadays imo.
One point though, during Op Uplift standards were dropped and all sorts were accepted, often before vetting was even completed-but in a market where you get more flipping burgers what are people going to choose?
