ICE doesn't actually wear badges as a rule; they usually just have a mask and body armor, with other clothing being random, often military-style items. Their body armor may say "police " or "dhs" but usually does not even say "ICE"
There's no real way to tell them from cartel gunmen.
The local cops also bear significant blame here; they took a cane from a blind man and beat him up and arrested him because they didn't have a language in common with the victim. This is what led to ICE taking him
We can make it into a bug if we're able to pressure him into recusing himself.
