Following a deadly attack on an immigration detention center, an app used to track federal law enforcement officers will no longer be available for download. Apple agreed on Thursday to remove the ICEBlock app, which uses crowdsourcing to track U.S. Immigration and Customs Enforcement (ICE) agents, from its App Store, facing pressure from the U.S. Department of Justice (DOJ) in the wake of a shooting at an ICE detention center in Dallas. The sniper, who wrote “anti-ICE” slogans on his bullets, reportedly used ICEBlock to track immigration agents and determine when to open fire.

“We just received a message from Apple’s App Review that #ICEBlock has been removed from the App Store due to ‘objectionable content,’” the ICEBlock developer said in post to left-wing social media website BlueSky. The developer added, “We have responded and we’ll fight this! #resist.” The developer has subsequently called on “everyone” to “install #ICEBlock to protect themselves and their communities. You can see reported ICE sightings within a 5 mile radius of your current location.” The developer added, “We must #resist in every way possible!” Although the app will be removed from Apple’s App Store, those who have already downloaded the app will be able to keep it on their phones.

“Based on information we’ve received from law enforcement about the safety risks associated with ICEBlock, we have removed it and similar apps from the App Store,” Apple shared in a statement. The iPhone manufacturer added, “We created the App Store to be a safe and trusted place to discover apps.” U.S. Attorney General Pam Bondi reportedly raised concerns with Apple over the app’s availability and how it jeopardizes the safety of ICE agents. “ICEBlock is designed to put ICE agents at risk just for doing their jobs, and violence against law enforcement is an intolerable red line that cannot be crossed,” she said in a statement. “We reached out to Apple … demanding they remove the ICEBlock app from their App Store — and Apple did so.”

Jessica Vaughan, director of policy studies at the Center for Immigration Studies, told The Washington Stand, “Apple has done the right thing in removing the ICEBlock app from its store, but it’s too bad that it took another fatal attack on an ICE facility and a formal request from the attorney general to do it.” She continued, “These attempts to resist and obstruct legitimate law enforcement can have deadly consequences, as we’ve seen. Not only that, the resistance is not going to protect anyone from deportation. If anything, it ups the consequences for those trying to resist.” Vaughan anticipated, “This will all die down at some point, but our law enforcement leaders need to stay vigilant until it does, and that means apps and other similar tools should be shut down to protect our officers.”

The removal of the ICEBlock app also comes as riots against ICE agents at detention facilities have increased in intensity, scale, and violence. Numerous Antifa rioters and agitators have been arrested by ICE agents in Portland. However, several reports have suggested that Portland Police are not arresting rioters but have instead been tasked with targeting federal agents. In one instance, a group of agitators, one of them dressed as a bird, set fire to an American flag. When reporter Nick Sortor took the flag and extinguished the flames, Portland Police arrested him.
