For example, if you forced the car thieves out of the car, or parked it in place by blocking the road, you might be looking at assault charges.
Similar arguments can be said for most other common crimes.
Consider noise ordinances (harassing / threatening your neighbor until they shut up), trespassers (Threats? Forcibly move them?), burglaries (rob them back?), domestic violence (victims that kill the assailant are often charged with premeditated murder), etc.
