From the AG, and current Gov, in 2017.
"Today’s decision is a victory for the rule of law and smart immigration and criminal justice policies, and a rejection of anti-immigrant policies that have stoked fear in communities across the country. As my office argued in this case, Massachusetts law protects our residents from illegal detention and prevents the federal government from forcing local law enforcement to make decisions contrary to the public safety interests of their communities. This decision allows local law enforcement to focus their resources on keeping people safe.”
"In the decision issued today, the SJC found that “Massachusetts law provides no authority for Massachusetts court officers to arrest and hold an individual solely on the basis of a Federal civil immigration detainer, beyond the time that the individual would otherwise be entitled to be released from State custody.”

The 8 year old kid will probably never be the same, but go ahead on with protecting the pedos.
