Doing investigative journalism in the best of times is a challenge -- getting the time to dig, developing reluctant sources, following compex trails.

How does an investigative reporter -- or an entire newsroom -- cope in a society that is closed, closing or captured? Here are some strategies for staying in business and fighting the good fight, from our resourceful colleagues in Cuba, Hungary, Myanmar, Pakistan, and the Philipppines.
