Lot of "Police bad" narrative. Some of it clearly totally justified.
But bear in mind what they're up against though. Assault numbers have triggered this post - in 2021/2 there were 41,000 assaults on Police of which 11,000 were "with injury". There there's all the verbal abuse they have to take and all the highly distressing situations they have to deal with through crime or accident - you might be stressed in your job, but you probably haven't had to decide whether to pull a trigger in a split second, or tell someone their loved one has unexpectedly died or seen child abuse or deal with those whose lives have been wrecked by drugs or fraud, or had to put your own life on the line. Quite apart from the feeling of the judicial system being loaded against them.
It never has been, and never can be, a role for shrinking violets. Mental and physical toughness is required. With the stresses they face it's unsurprising that some end up damaged.
All for fairly modest remuneration.
Rotten cultures and rogue officers have to be weeded out and dealt with. But the vast vast majority of officers are in the job for the right reasons and do the best they can in trying circumstances.
