A small investment in some inexpensive technology (namely GPS trackers) would easily weed out some major theft rings. Put some chips on some laptops, passports, bicycles, cameras, guns, etc. and follow them! They are all headed from little streams to one or two big lakes. Wait until you have them for 100 laptops and 50 passports and put them ALL away for a long sentence. There will likely still be some petty theft, but you would be able to put a huge dent in their plan, especially in smaller tourist towns.
Also, why not surveillance cameras in certain key areas? I can recognize exactly where there is major drug trafficking happening, why can’t the police see it?
