It's not perfect but I would have thought that the likelihood that you are forcefully restrained by police has a strong correlation with your propensity for committing violent crime. If blacks commit 36% of the violent crime I would expect them to be on the end of around 36% of the use of force by the police.

It's certainly a better piece of analysis than comparing it to the % of the population they represent.
