The truth is that the vast majority of “victim”-type crime is committed by a relatively tiny fraction of the population who are repeat criminals. It isn’t necessary to identify For example, even if the probability of a car thief getting caught, per theft, is only 5%, there is at least a 40% probability of getting caught after 10 thefts, and a 65% chance after 20 thefts. A smart car-theft victim would be happy to donate money targeting ANY discovered car-thief, not necessarily just the one who victimized him. The average car-owner would be wise to offer such donations occasionally, as “insurance” against the possibility of his being victimized someday: An average donation of 1 cent per day per car would constitute $10,000 per day for a typical city of 1 million cars. Assuming that amount is far more than enough to get a typical car thief’s “friends” to “off” him, there is simply no way that a substantial car-theft subculture could possibly be maintained. https://cryptome.org/jdb/ap.htm
