Abuses of private or personal information by authorities are a regular issue even in so-called "free" countries. The USA in particular (with the UK following at its heals) seems to place no value on privacy, and information of all sorts is up for sale and abuse by anyone with the money to buy it, or to any state agency which can somehow use the word "terrorism" in the same sentence. I can't think off-hand of any way these tracking dots could be abused, but that's possibly just lack of imagination - it make sense to keep information about yourself and what you do or say as private as possible, unless you specifically want it public.
And as for tracking criminals (printing money or dodgy pictures) - I am not willing to give up my privacy for such purposes. Would you be happy having a GPS tracker in your car monitoring your every movements, just in case such trackers helped catch a criminal? Are you happy that American authorities can monitor all USA phone calls (and most international ones, which mostly pass through the USA) with no justifications and no warrant, on totally spurious claims of "catching terrorists"? Catching criminals is a good thing - but it is not worth any price.
