TDP & VTA are spot on...
I have to agree... don't quit your day job, yet. Your salary should provide you enough income to feed your helicopter habit. Build your time slowly, but pay your mortgage and retain your financial stability. Get your PPL(H) in short order (fly 2-3 times a week until your ready for check ride), and then slowly build hours (2-3 times a month afterward). Keep looking for a flying job within law enforcement... eventually, you will find one and your skills and experience as a street cop will serve you well as a pilot.
