When the system is working the locals cops identify the specific criminal alien for ICE to come and pick up. This puts the local in control of who is picked up. It is not like ICE roams the halls of the jail looking for brown people as you imply.

They don't "roam the halls," but per ICE the request for detainer originates from them. Note the local official. The local doesn't have any choice in who ICE decides to issue a detainer for....at least according to what ICE says:
