Years ago I was told by a Chicago cop that they would not respond to stolen car calls unless the caller said they could ID the perp by name. Essentially that eliminated stolen car reports. No wonder the crime rate is so low in the windy shitty. “Rahmtown”
NJ cities have been doing this for years (long before budget cuts reduced them to smaller, middle-aged police forces). Everybody in NJ knows the crime stats are bogus, and they avoid certain areas accordingly.
