We have become so used to being treated unfairly by authority figures that we have come to accept that we deserve to be so treated.
But in truth, the reverse is also the case. We treat authority figures, particularly the police, unfairly too. For instance, we treat them unfairly to a low living wage and then leave them to their own devices. We fill them with the need to augment their income.
So, they ask for a bribe and we give it; we offer a bribe, they accept it. In exchange, they overlook our offences and allow us to get away with murder and avoid lengthy bureaucracy processes. Quid pro quo!
In addition, they get to keep whatever else they solicit at the roadblock and at 101 other places and occasions. A farsighted officer will put a chunk of this away for the rainy day or as a pension pot, because little or none may be coming from official sources after retirement. Certainly, here is one willy officer who will not be protesting over poor or unpaid pension in retirement.
