Modern Prisons afford many rights, privileges, access to good mental healthcare, and access to good regular healthcare.
You're kidding right. You can't seriously think that. Because in the US that's a load of bullshit. Our prisons are shitholes.
We don't treat people that need extra care well here. Take the case of trans women being thrown into male prisons despite their gender identities and is basically throwing them to the sharks.
"snip the vid"
OK, that is an unfortunate loophole in our justice system, right now the courts do not recognize transgendered women if they still have their "original equipment" (but most do recognize them as women if they installed the vajayjay). BUT here is the thing, how many countries in the world do? I bet I could count them on one hand, but even money for less then 10.
Are our prisons the best in the world, no, I think Norway wins that game. But we are in the top 10.
Is America perfect, no. Are we trying, yes. Is America safer than say Mexico or Brazil, Heck yes. Also, we do have geriatric (elderly care) facilities, many (even some first-world nations) do not yet do. We pass medication, that is only $3 dollars per prescription, not per/pill, 30 day supply. They have access to legal libraries, regular libraries, any religious organization you can think of and many more you have never heard of, they can even gain job experience that they can use as a reference when they get out. In fact, our prisons see a surge in population in the late fall when it is cold out, the Homeless/Vagrants know what laws too break so they get arrested and sent to jail for the winter, warm bed and three square meals a day.
Lastly, this does not apply to this case because Gary McKinnon is not becoming a woman (as far as I know). I just said all this because a prisons are a lot nicer then people give them credit. I would not want too live there only because criminals are there too.
