I was locked up in a mental hospital for ~3 weeks, during which time I found so many things that are wrong (but I don't have the time right now to write the whole story in full):
1. No cell phones, no internet access, very limited phone time -- why? The hospital is supposedly a place to heal, not a place to punish people.
2. No cameras allowed inside. Why not?
3. No personal possessions or lockers (I have trouble having > 2 books there)
4. The anti-psychotic drugs are... basically a scam.
5. Disregard of human rights.
6. Not even very hygienic there.
Sorry this is so brief; I will expand on all these later...
