Homeless facilities are inadequate in Massachusetts, and prisons aren’t full, so I understand your question. When Boston abruptly closed the Long Island homeless and recovery facilities in 2014, other homeless facilities in Boston were overwhelmed, and people who either couldn’t get in or couldn’t tolerate the crowds ended up tenting at Mass & Cass, which police have recently cleared out. Gov. Healy recently turned an old prison into an emergency homeless shelter, so there’s certainly a precedent: bit.ly/bscc-prison-homeless. But housing would be even better.
