Generally I oppose these types of laws because they are never used for the rare cases where Joe says John "hey John hand me your handgun so I can kill my wife" Instead most often these types of laws are used to prosecute people under a "should have known" scenario. Examples of real situations of 3rd party liability that have been used to send people to prison 1. Jim takes a friend to a bank, the friend goes in and robs the bank. Jim though the friend was just withdrawing some money from his account but Jim is arrested and convicted of aiding his friend in the robbery 2. Jane does not have a license, a police officer attempts to stop Jane, Jane panics and runs from the police. The Police officer runs through a red light while in pursuit and kills a bystander, Jane is charged with murder.
