A defense trick:
If you are in a crowd of advancing ICE or maga-cops you can drop strips of packing tape (the two or three inch wide clear stuff available at any drug or stationary store) or carpet tape (double sided super strong adhesive) in their path. It can really entangle an advancing phalanx.
(This trick can bounce back onto those who deploy it. It may be useful to tack one or both ends of the tape to the ground to prevent it from blowing back and entangling you, or if you have a coordinated group, anchor the ends to things like lamp posts.)
Nevertheless, do anticipate being arrested and perhaps billy clubbed.
