State-run click traps for internet surfers

After recent reports about the german BKA looking for suspects in the visitors of their web sites, now even more threatening measures against web surfers have been uncovered to be used by the U.S. FBI. After clicking on prepared web links (or after automatic download by browser prefetching...). the FBI searches the houses of those people whose IP addresses could be backtraced to their identities. One more reason to use anonymisation services like JonDonym which hides your IP from nosy eyes!
