I have spoken with some folks on the island about utilizing prisoners to mitigate the trash problem. It would serve two purposes,
1. Clean the streets 2. Send a message to future bad guys.
Put them in pink jumpsuits for further deterrent.
Give them an hour off of their sentence for each 8 hours worked.

Ever watch the big fires we have in California on the news? The guys in bright orange jumpsuits are all state prisoners. They cook and clean at base camps, cut fire line by hand, do preventative forest work, etc. Same idea.
