This sounds like a quick way to end up dead, enable Fox News to portray ICE as the victim and for ICE to use as an excuse to implement a policy of shooting first and asking questions later
If you wish to pursue this route be sure to look into what the Black Panthers did; namely not pointing guns at law enforcement or violating any laws; merely arriving in numbers with guns
The numbers is important. One person with a gun won't be able to tell their side of the story if they are killed by an officer
