Colorado: ICE raids at local apartment buildings

From an email from local allies:

Hey all,

Just a note to say I received a call about home raids in Aurora and someone detained in one and then just got off the phone with a\ friend in the Glenwood Springs valley who says the police and ICE have been cooperating in apartment complex raids up there…Tell the community: be careful. Look out the door before opening it, esp early in the morning. If they don’t have a warrant the person doesn’t have to open the door.
