My first day at San Quentin State Prison
Varun Singh

1 — cell phones have been used by inmates to continue 
their drug trafficking and to intimidate witnesses
so YES “a cell phone”

2- not feed the birds — even in the outside world there are signs everywhere 
to not feed the birds or any other kind of wild animals, because our food is not good for them.

If inmates cannot follow such simple rules then yes they are not ready for the outside where there are lots of places you cannot use cell phones — hospitals and driving for example
and lots and lots of tiresome rules to fit into society.

As for coming out after 20–40 years.
It is unimaginable how anyone can do that without a proper support system
and locking people up without any opportunities to rehabilitate or be educated is folly for the prisoners and for society.
