> First, WhatsApp is a US company and has no presence in Brazil. Under many readings of US law (specifically, ECPA), US companies are in fact prohibited from complying with requests from foreign law enforcement for content, except in emergencies. Instead, foreign law enforcement must make a request for assistance to the US DoJ, which will then (eventually, and maybe) process it and serve it on the US company. This is one of the reasons why MLAT reform, such as the proposed UK-US agreement[1], is so important because it would allow US companies to directly respond to foreign law enforcement requests. If you want to do business in a country then you should follow its laws.
