Where did you learn that cops get bonuses based on arrests? That's is laughably false and far from being true in any way. Please stop spreading such false info, it only goes on to perpetuate false narratives and promote the hate on police.
sorry i moved the train to far along on that statement which was ment as a joke/jab , There are indeed no Direct bonuses tied arrests.(although a google search will result in a scandal about that in San Diego)
There are however quota's in certain parts that are required to be met, naturally meeting these in a timely manner or getting more the required will lead into a "good" performance review increasing chance off promotion which naturally comes with a pay increase.
Based on that i'd say its fair to say cops are financially rewarded to make arrests perhaps indirectly but they still are, even if promotion wasn't on the table ,they'd be pressured to meet quota's to maintain job security.
no hate on cops,just things less morally inclined cops can use for personal gain, which is fair to point out.
