I have been doing all that you have suggested, and I have had literally years of training now. The duplex next door has done nothing but attract drug dealers, crack addicts and prostitutes for the past 8-10 years. I'm on a first name basis with the Special Ops lieutenant and the captain of Lansing's North Precinct. The captain has tried to help as much as he can, but he's pragmatic about the amount of money and manpower he has to work with. The lieu--everyone thinks this guy is a hero. I am slowly becoming convinced that he is, pardon me, nothing but an assclown. He seemed to take my recent call about the thug very seriously, even parked on the block to monitor the drug traffic...for two hours, 9am to just past 11am, last Friday. (Yeah, that is definitely the time of day when drug traffic is at its peak.) That afternoon, he called the new landlady of the property in question--who is taking this seriously--and told her I was getting hysterical over nothing. He didn't see any deals. She was furious. At least we have a drop-dead eviction date, and a good chance at getting that moved up. In this 'hood, we have a lot better luck with the city atty than the police.
Call the Chief and ask if this LT is related to the dealer. 11:00 AM, who the hell does he think he's fooling?
