If you're attacked by a mugger, or your car is stolen, or your house is burglarized, and you need police, good luck. There isn't a cash incentive for those kind of crimes, so those are low priority crimes when it comes to response initiation.
But if your neighbor call's them and tells them you're selling pot, not only will they show up, they'll show up in force, with their military equipment, automatic weapons, night vision goggles, armored personnel carriers, air support, canines, and all the cop accessories needed for a tactical take-down. All because if incentive. There's no money in it for them if your car gets stolen, if you get raped, or shot, or somebody steals your kid. But, if there's pot involved, there's big bucks, and the possibility of legalized assassination. Because the federal government gives them grants, and asset forfeiture gives them cash, and property, they have no reason to respond to regular crimes, none whatsoever. Why should they waste time and resources on non-profit crimes, when the big money is in busting victimless crimes.
An example: my moms van got broken into awhile back in front of her house. She knew who did it, the only juvenile delinquent on the block. She calls the cops, they show up, eventually, and couldn't care less. She had to tell them to fingerprint the sliding window with palm prints on it, and the reluctantly agreed, after she pointed out the prints. They took a half assed report, didn't even write down the address of the suspect she told them of, or his name, and that was the end of that.
Remember this next time you need the police, unless theirs a cash incentive in it for them, there's no incentive.
