Vote no in August

Since 2003 our I.P.D has recieved 14 million or so in grants, and yet here we are in AUGUST going again to vote yes or no for a sale tax increase for 42 or so more police.
My question is why? Where is all that money, now I know they don't have ALL that money now , but they still recieve grants from different directions.
I also keep asking myself why doesn't this city ask for the promise to pay loans back. What there is something around 12 million from Centerpoint, and  5 million or some from people that own property on Noland , and there are others.
