I'm planning on printing up quarter-page sheets on the importance your community plays in getting ICE to leave, and starting a Signal group for my neighborhood and including the QR code on there. Then printing a bunch of whistles and putting them with the flyers in mailboxes in my neighborhood.
I've printed a ton of these for a protest in the spring and they're super loud: https://makerworld.com/models/502788?appSharePlatform=copy
I printed a dozen of these and they're fast and cheap but maybe not as loud as the other (they're designed to print on their side): https://makerworld.com/models/2245044?appSharePlatform=copy
When I get home after the weekend I'm going to print these two to see if they're louder or cheaper/faster to print (or both!). If they are I'll use them for the above exercise.

Regarding putting anything in mailboxes - it is actually a federal crime to put something in a mailbox unless it is properly addressed for delivery through the postal system, or you are a postal worker. I would refrain from doing that.
