Are the detainee's being read their rights before they are handcuffed ? I would be fighting them
like my life depended on it, if they didn't ID themselves and read me my rights.

My understanding is that Miranda warnings are not required for immigration arrests, because they are civil (not criminal) detentions. And even in a criminal arrest, failure to provide a Miranda warning would only render your later statements inadmissible - it doesn't affect their ability to arrest you or the validity of the arrest, and would absolutely not authorize you to fight back against any law enforcement officers that have ID'd themselves to you (not legal advice, of course).
