Alex Pretti, a 37-year-old Minneapolis resident, was killed by Border Patrol agents on Saturday. The shooting has renewed protests after weeks of aggressive federal immigration action.  

The federal government’s account of what happened differs starkly from bystander video footage. Civil liberties groups say that’s exactly why independent observation and documentation of law enforcement actions is important.

Documentation can be a tool for accountability, legal challenges and public trust. But misunderstanding your rights can put you at risk.

MPR News guest host Catharine Richert explores what constitutional observers are, what rights they have and what can be considered interference.
