Not really a valid argument pro or con for ICE or anti ICE. ICE doesn't have a mission to kill anyone and has rules and established procedures on use of force and how it responds after a use of force incident.
Illegals have no such rules and commit way more criminal acts that result in the deaths of citizens than simple murder. To get anything close to an actual comparison, murder, drug deaths, ever things like drunk driving and other causality causing events would have to be included. You would also have to admit the obvious, illegals shouldn't even be here so the numbers of deaths blamed on them should be zero.
ICE has been held accountable for the deaths of suspects, but it is extremely rare and in the world of activist DA's and judges, even those examples may or may not be relevant.
