A lot of people lack the ability to do or credibly threaten sufficient violence for that to be actionable. Serving all the details up to the cops, who have nearly infinite ability to threaten violence, on a silver platter "here's your open and shut auto theft case, now go pad your stats" is the more tractable solution.

that is not that either though or is it? i mean say i found my vehicle on some platform for sale and then located it with their service, now what? i call the cops i suppose, i dont see how this is much different to calling them once they agreed to meet somewhere.
