Knowing when a criminal gets out of jail and is an illegal-- that is public knowledge! Nobody is stopping or needs to cooperate on this. ICE can't even bother to look up the criminal in jail
The Gov't puts a detainer on criminal illegals in jails, but the police fail to alert the Gov't when they are released. If you want ICE/DHS to sit at the jailhouse around the clock and stop everyone to see if they are subject to a legal order to deport, just say so - but that's gonna take a lot of agents.
We have cities that refuse to hand over criminal with deportation orders to feds - because somehow, keeping them in their community makes their community safer? Really? I would think REMOVING convicted child rapists, drunk drivers, wife beaters, drug dealers, etc in the country illegally would make the communities safer...
If you want to 'peacefully protest' ICE, fine, but the moment you strap a gun to your waist and then decide to start a physical altercation with an armed federal agent, you run the risk of being shot. If you provoke federal agents, taunt, insult, and dare them to arrest you and THEN (even accidentally) drive your car into a federal agent, you again run the risk of being shot. Neither of the two shooting victims were 'peacefully protesting' - if you touch a federal agent, that's assault, not 'peaceful'.
