Ok then, so more technically, and more generously to police from a purely reactionary perspective of 'they can only respond to reports'... they do an adequate job of clearing 4% of what actually gets reported to them.
I know that cops dont actually prosecute, I made that post before falling asleep, I was a bit loose with language.
Their role in the prosecution process is basically to be witnesses, to gather evidence for the trial.
And, unless I am misunderstanding this... ~82% of the arrests they do actually make ... don't result in convictions, and are thus 'overarrests' in some sense... as ... you went to all the effort to make an arrest, and it turns out that no actual crime was committed?
Cops have an ~18% chance of making an arrest for a serious crime that actually sticks?
They have an ~82% likelihood that they are overpolicing, like by definition, when it comes to serious crimes?
