Why should person A pay restitution for person B? Person A likely isn't granted powers of law enforcement and so has no means of preventing the crime. How can person A prevent a crime caused by person B? They cannot. Situations happen. People commit crimes for the first time every day (shocking even close family members). People like serial killers (and many other forms of covert criminals) may go undetected for decades with those people having perfect records. Since crime cannot be prevented by a landlord and cannot be completely avoided, what can that landlord do to mitigate their risk? They must discriminate. They look at groups which appear to commit disproportionate crimes (by whatever "metrics" they choose to look at) and then start cutting away. Bad credit, being poor, being the "wrong race", prior convictions -- the list of risks seems endless. The law (with very good reason) prohibits this kind of profiling, but that causes a catch 22 in the mind of the landlord, so the discrimination simply happens in a less-obvious manner. Meanwhile, these people are shifted into bad neighborhoods and ghettos to become trapped forever and crime continues on regardless. Since no crime is prevented (at most, its only moved elsewhere), the law is ineffective. That would be bad enough, but it also proceeds to punish the landlord and a long list of underprivileged people. The cure is definitely worse than the problem.
