What I know about Alcatraz is not a whole lot. But what I do know is this.
It was(is?) an Islandic Maximum security prison. I do recall people always saying. Escape from alcatraz is impossible. Also I don't know how many escapees they had, but I don't think it was all that many.
Anyways the conditions of the island weren't nice if I recall right.
I believe they had thier own generator. The water was extremely rough, making swiming an unlikely feat. At least it was something like that.. or I hope I am thinking of the right prison...
But yeah.. definately High-security.
