These are the towns that have rich elitist people who think their shit don't stink, starting with the mayor and town council. They have huge LE budgets but low crime numbers so most of the LE are sitting on their asses all day scratching their balls. So they pass the time by over-policing HS kids, finding minorities to pull-over or harassing the "unwanted" businesses, like AMP's or vape shops.
I remember passing a typical fender bender while driving through Wyckoff on my way to work, just two cars in a typical accident, no injuries or anything, and there were 4 or 5 squad cars surrounding the scene. Yup, taxpayer money at work. 4 lanes of a major street in town and they had so many squad cars blocking three lanes and snarling traffic for a mile.
I'd also add most of the towns in north Bergen County to the list, but specifically Glen Rock, Allendale, Saddle River, Upper Saddle River, Paramus, Mahwah.
