In the wake of Trump’s immigration crackdown, activists are building apps to fight back

The Trump administration continues to detain, expel, and imprison thousands of Americans for the most cruel and arbitrary reasons.

In response, tech-savvy users are taking to social media platforms and encrypted messaging apps to warn their communities, in real time, of encroachments from immigration agents.

Some are even going beyond that—by building their own tools to fight back.

ICEBlock was created by Aaron Aaron , who worked for Apple in the early 2000s .

Aaron says he stands by the legality of the app, which includes a disclaimer against “interfering with law enforcement” The app is not available on the Google Play Store because its terms require that the ID of every user be stored in a database that would make it possible for any government official to subpoena the developer.
