While I don't know how many interactions there has been, according to https://www.washingtonpost.com/investigations/interactive/2022/police-misconduct-repeated-settlements/ https://www.washingtonpost.com/investigations/interactive/20... for example New York has had over 10000 officers involved in cases where they settled ("46% by officers named in multiple payments" "more than 5,000 officers were named in two or more claims") across 10 years. They seem to currently have 36000 officers, I don't know how long they stay on the job on average or how the numbers have fluctuated over the years, but even if it's just 1 year and their size hasn't changed that would mean about 2.8% of police force in NYC was involved in misconduct that resulted in settlement. These don't include number of cases where legal action wasn't taken or which got thrown out due to qualified immunity (these are somewhat related, if case is unlikely to get past qualified immunity it's quite unlikely legal action will be taken). And probably cases which actually went to trial as it seems to focus on settlements. Additionally there is for example https://www.nyclu.org/en/publications/cop-out-analyzing-20-years-records-proving-impunity https://www.nyclu.org/en/publications/cop-out-analyzing-20-y... which covers 2000-2020 misconduct complaints. According to it disciplinary actions were taken 4283 times, meaning that even if conduct was enough to reach settlement it doesn't necessarily mean it results in any actions taken against the officer.
