Whistle Alert System
Whistles are simple tools for fast alerts. From what we’ve seen in other cities, whistles are an instant alert system that’s faster than social media, and can help protect neighbors in real time. For some, it’s a signal to hide and stay safe. For others, it’s a call to action: to gather, to get loud, and to make it impossible for ICE to move quietly through our neighborhoods.
CODE 1 – ICE IS NEARBY
- Sound: Short, broken rhythm
- Pattern: TWEET – TWEET – TWEET
CODE 2 – ICE IS DETAINING SOMEONE
- Sound: Three long blasts
- Pattern: TWEEEEET – TWEEEEET – TWEEEEET
COMMUNITY RESPONSE: WHEN YOU HEAR A WHISTLE! (FOR ALLIES)
If ICE is not targeting you, use your safety to protect others. In cities like Chicago, LA, and Portland, neighbors have protected each other by acting fast and acting together. Remember: community defense is not one heroic act, it’s about many people moving together as one.
IF YOU HEAR A WHISTLE:
-
- Come outside and look around.
- Shout and bring out more neighbors. The more people are visible, the safer it becomes.
- Record if it’s safe. Focus on agents and vehicles, not community members. Do not film children’s faces.
- Make noise. Use your whistle, your voice, or a blowhorn to draw attention to where ICE is located. You can also shout “ila Migra! ICE!”
- Share information with trusted organizations like Immigration Defense Project (212-725-6422).
- Center those impacted. Ask what they need and protect their privacy.

Haha, so a whistle is faster than Twitter now? Who knew? Seems like a more reliable alert system than waiting for a tweet to load. But seriously, community defense isnt one heroic act, its about many people moving together as one? Sounds suspiciously like a plan for a very large, very noisy game of Simon Says, but with ICE instead of just Simon. Good luck coordinating that! #TeamworkMakesTheDreamWork (Or gets you noticed by ICE?).
