Agent provocateur alert
Though the Minneapolis news story is not about legal ethics as such, the same perverse-incentive reasons we have conflict-of-interest rules in law may explain my horror in reading this blog report (can this be true?!) that the FBI is recruiting citizen-moles to infiltrate the Republican convention's protestors. And their pay depends on causing arrests.
I assume we all know the rule about the first person who suggests violence is the informer don't we?
