Prison is an Educational Institution

And arrest warrant is your proof of enrollment at this higher education facility, therefore you're entitled to free versions of professional software, such as Photoshop, and have a complete right to steal it for educational purposes. There is absolutely no difference between "correction" and "education", unless you're a punitive justice mental midget.

Prove me wrong.

That doesn't apply to the army though, because army is your own decision to waste time, but if you openly refuse to serve and get prison sentence for draft evasion, you can consider yourself entitled to all kinds of benefits and have complete right to steal anything you need.
