Lotsa guys come in talking/acting crazy, anyway. You will fit Right In....
All you have to do is say : "suicide" or just imply it or appear too "excited"--and , same thing happens:
You go to a windowed observation room, with restraints on a flat table and have to wear as big, padded toga. No underwear. If restrained, IDK how u get fed. Some say, a tube thru the nose but, actually, forced-feeding is illegal. If you are not restrained, a tray comes thru a slot in the door. . You return tray when finished thru same slot. If UR are deemed OK for gen pop in a week, you go back. If not, to ASH (Arizona State Hospital , for mental cases in prison.) Might get lithium or phenobarb shot if too violent.
You Cannot carve Anything on concrete. You wont have anything sharper than a pen/pencil or plastic spork at anytime.
